Although the U.S. is one of the richest societies in history, it still lags behind other developed nations in many important indicators of human development -- key factors like how we educate our children, how we treat our prisoners, how we take care of the sick and more. In some instances, the U.S.'s performance is downright abysmal, far below foreign countries that are snidely looked-down-upon as "third world." Here are six of the most egregious examples that show how far we still have to go:

1. Criminal Justice

We all know the U.S. criminal justice system is flawed, but few are likely aware of just how bad it is compared to the rest of the world. The International Center for Prison Studies estimates that America imprisons 716 people per 100,000 citizens (of any age). That's significantly worse than Russia (484 prisoners per 100,000 citizens), China (121) and Iran (284). The only country that incarcerates a higher percentage of its population than we do is North Korea. The U.S. is also the only developed country that executes prisoners -- and our death penalty has a serious race problem: 42 percent of those on death row are black, compared to less than 15 percent of the overall population.

Over two and a half million American children have a parent behind bars. A whopping 60 percent of those incarcerated in U.S. prisons are non-violent offenders, many of them in prison for drug charges (overwhelmingly African-Americans). Even while our crime rate has fallen, our incarcerated population has climbed. As of 2011, an estimated 217,000 American prisoners were raped each year ­-- that's 600 new victims every day, a truly horrifying number. In 2010, the Department of Justice released a report about abuse in juvenile detention centers. The report found that 12.1 percent of all youth held in juvenile detention reported sexual violence; youth held for between seven and 12 months had a victimization rate of 14.2 percent.

2. Gun Violence

The U.S. leads the developed world in firearm-related murders, and the difference isn't a slight gap -- more like a chasm. According to United Nations data, the U.S. has 20 times more murders than the developed world average. Our murder rate also dwarfs many developing nations, like Iraq, which has a murder rate less than half ours. More than half of the most deadly mass shootings documented in the past 50 years around the world occurred in the United States, and 73 percent of the killers in the U.S. obtained their weapons legally. Another study finds that the U.S. has one of the highest proportion of suicides committed with a gun. Gun violence varies across the U.S., but some cities like New Orleans and Detroit rival the most violent Latin American countries, where gun violence is highest in the world.

3. Health Care

A study last year found that in many American counties, especially in the deep South, life expectancy is lower than in Algeria, Nicaragua or Bangladesh. The U.S. is the only developed country that does not guarantee health care to its citizens; even after the Affordable Care Act, millions of poor Americans will remain uninsured because governors, mainly Republicans, have refused to expand Medicaid, which provides health insurance for low-income Americans. Although the federal government will pay for the expansion, many governors cited cost, even though the expansion would actually save money. America is unique among developed countries in that tens of thousands of poor Americans die because they lack health insurance, even while we spend more than twice as much of our GDP on health care than the average for the Organization for Economic Co-operation and Development (OECD), a collection of rich world countries. The U.S. has an infant mortality rate that dwarfs comparable nations, as well as the highest teenage-pregnancy rate in the developed world, largely because of the politically-motivated unavailability of contraception in many areas.

4. Education

The U.S. is among only three nations in the world that does not guarantee paid maternal leave (the other two are Papua New Guinea and Swaziland). This means many poor American mothers must choose between raising their children and keeping their jobs. The U.S. education system is plagued with structural racial biases, like the fact that schools are funded at the local, rather than national level. That means that schools attended by poor black people get far less funding than the schools attended by wealthier students. The Department of Education has confirmed that schools with high concentrations of poor students have lower levels of funding. It's no wonder America has one of the highest achievement gaps between high income and low income students, as measured by the OECD. Schools today are actually more racially segregated than they were in the 1970s. Our higher education system is unique among developed nations in that is funded almost entirely privately, by debt. Students in the average OECD country can expect about 70 percent of their college tuition to be publicly funded; in the United States, only about 40 percent of the cost of education is publicly-funded. That's one reason the U.S. has the highest tuition costs of any OECD country.

5. Inequality

By almost every measure, the U.S. tops out OECD countries in terms of income inequality, largely because America has the stingiest welfare state of any developed country. This inequality has deep and profound effects on American society. For instance, although the U.S. justifies its rampant inequality on the premise of upward mobility, many parts of the United States have abysmal levels of social mobility, where children born in the poorest quintile have a less than 3 percent chance of reaching the top quintile. Inequality harms our democracy, because the wealthy exert an outsized political influence. Sheldon Adelson, for instance, spent more to influence the 2012 election than the residents of 12 states combined. Inequality also tears at the social fabric, with a large body of research showing that inequality correlates with low levels of social trust. In their book The Spirit Level, Richard Pickett and Kate Wilkinson show that a wide variety of social indicators, including health and well-being are intimately tied to inequality.

6. Infrastructure

America is a great country, and it does many things well. But it has vast blind spots. The fact that nearly 6 million Americans, or 2.5 percent of the voting-age population, cannot vote because they have a felony on record means that politicians can lock up more and more citizens without fear of losing their seat. Our ideas of meritocracy and upward mobility blind us to the realities of class and inequality. Our health care system provides good care to some, but it comes at a cost -- millions of people without health insurance. If we don't critically examine these flaws, how can we ever hope to progress as a society?
