Earlier this year, a Yelp employee publicly complained to the CEO that she couldn't afford to buy groceries, thanks to the combination of making an $8.15-an-hour after-tax salary while living in the notoriously expensive San Francisco Bay Area.

Hours later, she was fired, which sparked a lively dialogue.

She saw "an outpouring of support, including donations to her personal PayPal account," Business Insider's Matt Weinberger reported. She also received a cacophony of criticism, including a brutal response from one millennial that went viral.

But Talia Jane (not her full name) certainly isn't the only one having trouble making ends meet.

According to the Bureau of Labor Statistics, 4% of all hourly paid workers (about 3 million people) earn the before-tax $7.25-per-hour federal minimum wage or less.

Pew Research Center found that 30% of hourly workers (about 20.6 million people) are "near minimum wage" workers — those who make more than the minimum wage in their state but less than $10.10 an hour.

Many states and cities have set their own, higher minimums. For instance, the before-tax minimum wage in San Francisco is $12.25 an hour, and it will be $15 an hour by July 2018. In New York City it is $9 an hour but also slated to climb to $15 an hour.

Is it really that hard to make ends meet with a "near minimum wage" or otherwise limited salary? To find out, I decided to simulate living on Jane's salary for 30 days. I didn't quit my job — I put the overflow in savings, which sets my situation apart from Jane's immediately. I'm also based in New York City rather than San Francisco, but considering that the two cities trade off the title of "most expensive in the US" depending on the list you're reading, I felt comfortable with the comparison.

Note that my experience has to be and has been different from hers, and it was worlds away from the millions of Americans who live on minimum or nearly minimum wage day in and day out. Even with the advantages that come with higher pay, including benefits and a safety net of savings, it was difficult. I can't imagine what it must be like to have a consistently limited income. After only a month living on $8.15 an hour, I can say: It's even harder than it sounds.
