"According to the Fair Labor Standards Act Amendments in 1996, employers are allowed to pay workers under 20 years of age $4.25 per hour for the first 90 days of employment.Employers are not allowed to replace current workers with employees under 20 and are also not allowed to fire them before the 90-day window has elapsed, but it still provides an opportunity for exploitation for employers who want to hire cheap workers."
For context, I had my first summer job at age 16, selling woolen clothes door-to-door in July, paid on commission only. After the first week I had spent more parking my car at the business than I had made in commissions, so my mom helped me find a job in a Green Giant pea-packing plant in rural Minnesota. Twelve-hour shifts, seven days a week at minimum wage (unless it rained in which case you didn't work). I told that story back in 2010.
And for further context, my mom started working on her parents' farm when she was old enough to hold the reins of a team of horses that pulled the cultivator (a hired man would put the horses into harness). Neighbors said it "looked like there was a big straw hat riding the cultivator."
