It's not a matter of getting paid less for the same job, it's a matter of not having the same skills or experience. Employers need some incentive to take a chance on someone with no employment history.
We should stop worshiping at the alter of "small businesses". We've done it for decades and I'm not convinced it has helped in the slightest. Small business owners have the worst victim complex I have ever seen.
We've all seen this flip before and I think its disingenuous to pretend it doesn't apply here because its "low skill". this leads to us being okay with someone making less than the minimum wage and pushes downward on labor's ability to attempt to make the playing field livable, not level, just livable in a way that we could be proud of as a nation rather than embarrassed of.
Let's push it further: can we say the same for very experienced employees? Isn't the employer taking a chance on the employee being willing to learn and adopt a potentially different workflow? Maybe we deduct from the value of a highly experienced employee due to the likelihood of them being stuck in their ways. Oh wait that's ageist now isn't it.. Funny how that double standard works.
