Blue card minimum salary included in the above link. Hard to know if you'd come out ahead given local cost of living, but you can also probably beat the blue card minimum for your salary in the Netherlands. I know a couple people who make > 100k euros (some contractors, some who have made it pretty far up at bigger companies.)
