Because they can, because this is how natural selection works, because this is the soul essence of the capitalism, because cartels and monopoly is what they want to become at the end of the day to squeeze even more money and suppress any concurrency in the process (nothing personal for them it is just a survival strategy). The better question is why are they allowed to be like that? The short answer is money. The politicians are cheap to buy these days. The longer answer - no body gives a fck beside those wich are loosing money. Most of the population does not even understand what exactly they are loosing. Take an IBM for example, they are known to kill any concurrency for decades already. Nobody gives a fck.
