I was thinking if there is only one mobile phone company in a country then there will many free services such as "unlimited free calls to 10 users or 20 users". When we call different mobile company users we are charged money. But there are free call service for upto 5 users of same mobile company. Also when there is only one mobile company there will be no expensive TV advertisements from the mobile company. So ultimately consumers will benefit because consumers ultimately pay TV advertisement cost. Competition leads to TV advertisements and other company service charges which ultimately leads to inflation. The same applies to other industries and products also. Monopoly reduces final selling price and further reduces inflation. People power can bring down governments so people power will easily bring down monopoly company if they are doing something wrong. There are honest giant companies who want to rule the market. People power can always control the monopoly company.
