Re: I'm a STEM graduate migrant worker in the US that's trying to hire people... (@Blake)
On the contrary; if I were a Republican I'd believe that a free market would set appropriate wage levels. I wouldn't invest my faith in a market so artificially hobbled by immigration caps that both sides of the aisle agree that reform is necessary. If I were a Democrat I'd probably be concerned about the growing wage gap between those with a skill the immigration system does recognise and those without, created entirely by an artificial cap on availability of the former. If I were simply an American I'd be concerned that there's an area of the economy that could be more productive — producing more tax and benefitting everyone — but doesn't have enough labour to grow.
In practice I'm none of those things so to sum up the problem for you: an artifificial government measure has created a distorted market. The market itself doesn't want the measure and I can't see why anybody else would either.
I don't agree with your reply because I don't agree that the market is functioning.
