Paris Very Expensive City

In my opinion the Effil tower of Paris is the most expensive location of this world. Price of everything is more then double. Even I realise that this city is very very expensive.
Main problem with planner of that city is that they want to earn lots of money from Tourist of that city. They think Tourist as sole income provider for there city. They don't focus on another source of income for there city. In my opinion due to this type planning comman man want to live away from the beauty of this city. Cost of anything is more then expected and even not justified for comman man.
