Thanks. You once said if our pretax income doubles from 100k to 200k, our after-tax income increase by 20k? I feel that's unlikely.

The first 100k is probably taxed at 20%, for any rich or poor family.

The next 100k is probably taxed at around 50%. Not at 80%.

By the way, now I  know how much a new Masters' graduate from a good university can earn as a developer.

* morgan stanley pays about 75k base
* microsoft pays about 85k base
* google pays about 90k base
* amazon pays about 100k base

If you worked a few years before coming to the US for masters, that experience basically is worth $0.
