Compare that to thousands of people dropping out of the education system early to do unskilled factory work because it pays well above average salaries.
Imagine for example you could make $120,000 a year as a programmer, or $200,000 a year doing factory work. Do you think society will produce more programmers or more factory workers?
Imagine what happens a few years down the line when the multinational that owns the factory decides to up and move to another country in order to reduce costs.
