Unpaid or low-paid internships, during which novitiates gain work experience and a line on the resume, and maybe even learn some useful skills, have come under attack lately. It is argued, and probably correctly, that only the young people who have some other means of support (well-off parents, trust funds, built-up savings, etc.) can afford to take these positions (vs what? working at a fast-food place?).
Regardless of the merits of the arguments, here is a conditional prediction:
If unpaid and low-paid internships are banned by law, some firms that currently offer low-paid or unpaid internships will open ancillary training academies that just happen to charge approximately what the legislated salary would be minus whatever the current salary (or zero) happens to be.
This work around to sidestep a ban on unpaid or low-paid internships would be somewhat more costly than the current situation (or else it would be in place already) but with time and practice it would roughly approximate the current situation.
Some young people looking for work experience and resume lines are willing to work for low salaries, and some firms are willing/eagre to accommodate them. They will find a way to reach mutually beneficial arrangements.
People respond to incentives.
