Age discrimination comes to mind. My honest opinion is age shouldn’t have anything to do with your wage. Everyone is different. To me, the ideology behind this is: “the older you are, the more experience and/or maturity you’d have making you more of an asset to a potential employer than someone younger.” I’m in a major metro area near a university and sometimes get 18-19 year olds that come in and are way better employees with better experience than some that are in their mid 20’s with similar experience. Having experience also isn’t always a good thing. You, as the potential employer, don’t know what those experiences were exactly. They could’ve been good or bad. I believe employees should get paid based off of their skill level and ability, not age.
Economically speaking, this is could be a disaster for anyone 22+ trying to get an entry level position and could possibly lead to an unemployment gap. What if you want to get a new job in a new field with no experience in that field? What company would hire a 22 year old for 7.61/hr when you could hire an 18 year old for 2.00/hr less for an entry level position? This promotes discrimination and in my opinion, would not work in the U.S.
