I think it's a good idea; however, it has to be implemented in such a way so as not to hurt the ones it's meant to help. I'm going to go to the extreme and give you an example of what I mean.
Last year at the federal labour code hearings, someone next to me was representing people with disabilities. He suggested that people with disabilities should be paid less than the minimum wage, to which everyone was almost shocked.
He said they will always receive certain benefits because their physical disabilities require therapy anyway. No salary will actually allow them to have that kind of physical therapy. But if an employer has to pay a minimum wage for him, fortunately, he has two arms and two legs. A minimum wage for someone who doesn't have an arm is such a high risk and it's such a great expense that it actually hurts them.
This person was representing people with disabilities. When talking to him, I learned that's the extreme case. But I think you want to have the kind of policy that will help people, not exactly hurt those it's meant to help.
It's a great idea, but implementation is not going to be easy.
