Quality is how employees are valued in a business. That's how salaries are made. Overpaying in an industry is just a big of a problem as underpayment, it's far from a free market as you think.

Point based systems work in many countries very well, I don't know why you think "paying" for citizenship is the answer. What's stopping anyone in the world to simply pay a troll company for guaranteed live and work status in the US?
