Salaries in the US seem really high compared to those in the Netherlands. I have 2 bachelor and 2 master degrees in STEM. I made €10/hour (about $12) giving private math and programming lessons, while I earn roughly €13/hour (about $15) at my entry level job (after tax deduction).
I would expect my salary to grow at my current job. I also feel that I would have been hired at my current job if I just had my bachelor degree.
