Why do you think 'Bangalore' became a verb?
In most non-managerial posts, even if you paid me half the equivalent of what you get in the US, i'd still be living a comparable life here. That's what I meant by cheap economy.
If I got $1000 from RA/TA(etc) a month in a US grad school, I'd be making more (face value) money than professionals with 4-5 years of experience here. But I can do way more with that money here. I'm spewing out gibberish, but I hope you get my idea. :\
