Turning Down 120K and Trading it for 20K

Dilbert has turned down a job offer that pays him 100K
USD a year (in current exchange rate) excluding benefits
: 27 days a year vacations and health benefits, employer's
contribution for pension and he will be solely responsible
for software team. But he has turned it down. That is a
hard decision for him. He will go for PhDship that will pay
him only US $20K p.a. So he has traded 20 for 100? 120?

He has not sworn to stay poor and his 20K is tax free, it
leads to a PhD degree, he can qualify for CTO jobs and he
may run his own firm before the PhD ends. Who knows :))

So he thinks he is right and perhaps MBA learning journey
is a factor too. Perhaps he is justifying himself for push and
pull forces too. Well everyone has to make own judgement
calls and bear consequences, so will be he! Time will tell.
