A lot.
If u do not consider the recession I can give the following examples:
1. 75% of the people are well settled. They do not bargain in market due to their big income. It has become the reason to increase in price of all non-packed products like vegetables, masala chats, Hotel prices, Auto-taxi charges, carpentary charges, Real-estate and so on.
2. Kannada Film industry developed rapidly in last 5 years. Because IT people go for all language movies including kannada in the weekends. Also as I mentioned in (1.) due to great business for autodrivers, market people, MNC security guards housekeeping boys etc. watch the movies.
3. IT also helped the other businesses like cateing, security, housekeeping, transporting facilities, Air conditioning business etc to grow up. This created more jobs. These jobs created more business transactions.
4. If you compare the price of entry ticket for Bangalore cricket ground with the other cricket ground you will come to know how the cost of living in Bangalore is increased.
5. The Pub culture and Prostituism is also increased. Because only in IT industry you can find more than 90% of people below 35 years of age.
6. There is nobody to buy second hand bikes, second hand electronic items etc here.
7. Cable price is also increased. If you ask for discount they will say "if you want pay this much amount, otherwise I will disconnect" We face similar answer in vegetable market, textile shops and other places.
