Topic: Monopoly
I think one of the major problems of tomorows economy will be the forming of monopolies. There are rules and institutions in the western world to prevent this, and they do work, but some compagnies seem to find a hole. After all, it is very difficult to make good laws for this particular issue. Considering the amount of money involved, the risk for corruption is rather high.
Personally I don't see a simple answere to this problem. But it is a real threat.
There is one exception were you create a problem with a simple sollution. Sometimes when big gov institutions got privatised, they have a large chance of having a monopoly in a certain market. In this particular case, they can split it up and make sure it gets devided between enough different parties. For most other cases though, its far more difficult.
Please don't turn this into a tax debate unless it really has to do with it. There are enough other threads about that.
