The opposite of "disincentives to not hire" is "incentives to not hire". Or, you could oppositize it this way, "Disincentive to hire."
So, following his logic, the FIRST thing employers need is more incentives to not hire people..... because they're hiring too many people at the moment, right?
Double negative makes a positive in math, and it does in this sentence, too.
Someone needs to give politicians plain-language lessons. Just say what you mean, folks. It's as simple as that!
