Instead, we live in a world where nothing goes untaxed. About 1/3 of Americans say that their expenses are so high that after the theft of the federal government from their paychecks, they need a "side hustle" to make ends meet. According to Bankrate, side hustlers make $1,122 per month on average from their part-time work — up from $686 last year. But if Americans were given the right to no longer be stolen from, and got to keep their own money, most wouldn't need a side hustle or part-time work to get by.

Nearly half, 45%, of U.S. workers earn additional income outside of their primary career, a recent Bankrate survey found. This includes 48% of millennials. The percentage of Gen Xers and baby boomers with a side hustle is slightly lower, coming in at 39% and 28%, respectively.

"A lot of people are working side hustles because even though the economy is strong, wages are stagnant," Amanda Dixon, an analyst at Bankrate, told MarketWatch. 

"For a lot of Americans, expenses are rising, but there are no raises at work."
