That depends on whom you asked. From my perspective the world was a better place in the past but that's my personal opinions.
Has India become a better country because of all the offshoring? Their GDP might increase, but what about their quality of life? What about those overwork IT workers?
There are 2 things I learned in life so far:
1) There's this thing called "balance".
One gives, the other receives. One gets something, the other lose something. Addition, subtraction.
2) Money is the root of all evil.
I've never perceived that money can make the world a better place. In 1998, money nearly destroys Asia. In 2008, money hurts western countries.
US residents probably have more money than the other countries. But at the same time, check out the obesity level of US residents. Check out how many trash US produces. Why do you think people are buzzing over "green" thing.
If you have more money, you will want more of everything. The end result of this cycle hasn't been good so far.
As of today, the world has more problems than it was. Eliminate one, then two or more problems will arise.
