The Congressional Budget Office reveals shocking forecasts for immigration, debt and spending for the next 30 years...

How do you know a politician is lying to you? Simple: His lips are moving.

Yes, it’s an old one - but none the worse for that.

The 2020 election season is getting into full swing. Politicians on all sides are ramping up their rhetoric, including their promises, forecasts and accusations.

But it’s fascinating what you can find out if you just read official documents. Especially some of the fine print.

And here are 10 remarkable forecasts and assumptions that Washington is making and isn’t telling you. These are all contained in the Congressional Budget Office’s most recent Long-Term Budget Outlook, the cornerstone document of government financial and economic planning.

1. We’re going to have a lot more immigrants. A lot. They’re expecting a net 22.5 million more immigrants to come to the U.S. over the next 20 years. By 2049, they’re expecting immigration to account for a stunning 87% of annual population growth. 2. We’re going to have a lot more illegal immigrants. Despite the current bluster and the scandals at the border, the CBO expects we’ll have 2.4 million more illegal immigrants (or “undocumented residents,” or whatever) in 20 years’ time than we have today. 3. We’re going to be up to our eyeballs in debt. The national debt is expected to skyrocket to an “unprecedented” 144% of gross domestic product by 2049, or twice the level today. That would put the debt just under $100 trillion. The figure today: Around $18 trillion. As recently as 2000: $4 trillion. Oh, and this isn’t even the worst-case scenario: The national debt could exceed 200% of GDP in 30 years’ time, the CBO acknowledges. 4. We’re going to owe so much money that by 2049 the annual interest on the debt will be about 5% of gross domestic product — roughly the share that we spend today on Social Security. And that’s even if interest rates stay low. Despite rising debt and federal spending, the government is expecting — or hoping — the average rate on federal debt will rise only from today’s lowly 2.4% to 4.2%, still modest by historic standards, by 2049. 5. This debt, and these deficits, will damage the economy. They will crowd private investment out of the debt markets, reducing income and growth, says the CBO. And as we’ll have to borrow more and more from abroad to finance the government, they’ll lead to bigger and bigger interest payments leaving the country. 6. Social Security, Medicare, other health programs and net interest are going to soak up so much of the budget that we’re going to have to slash everything else to the smallest share of the economy in 70 years - just 7%. The average over the past 50 years: 11%. 7. Just to keep the federal deficit to these levels, your taxes will go up. The Obama tax hike on “Cadillac” health-insurance plans will kick in starting in 2022, and the 2017 Trump tax cuts will expire in 2025. 8. Most working stiffs can say goodbye to any other tax cuts. Uncle Sam is explicitly relying on your taxes to go up thanks to “bracket creep,” where income-tax brackets rise only in line with inflation while your income — you hope — rises faster. 9. While tax rates go up for most people, they won’t for those earning the most. That’s because more and more of their income will be above the Social Security “cap,” saving them an effective 12.4% a year. The cap this year is $132,900. 10. Meanwhile, working stiffs will be taxed at twice the marginal rate of those who live on dividends. By 2049, says the CBO, labor income will be taxed at a marginal rate of 32%, compared to just 16% for capital income. Good to know, isn’t it?

It would be great to see some of this stuff come up in the presidential race, wouldn’t it?
