What I'm saying is that, if you insist that monetary compensation for a particular job must be no less than a certain amount, then all other benefits (insurance, training, experience) will be limited by that.

A job that does not confer many added skills or valuable experience may therefore be available for that wage, but one where much of the compensation is training may not be available at that wage price.

It's not a case of "apprentices making more money" vs. "apprentices making less money". It's a case of "apprentices making less money" vs. "apprentices not hired at all."
