Everyone will agree that Western people changed the world in the last 100 years starting with Machineries, Automobiles, Electricals, Electronics, Computers, Internet, Mobiles etc. But there is always some saturation for any invention. We have invented a lot of things and now the invention will become slow in the future and mass production industry will be growing more and taking these inventions to all the people around the world (For eg. TATA is planning for a 100K INR for a car). This means western countries growth will be slowed down and countries like China, India will have more growth in the near future. I don't think of anything big invention will happen other than alternative fuel. This doesn't means the quality of life of an Indian or Chinese improve. We all be more rich in terms of numbers (any currency) thats all. You can see in papers and tell that you earn equal to a guy in London or New York and live in a house worth 300K USD or 100k BP. But still we need to struggle for good water, good food etc in our daily life.
