"I don't have a problem with Google, Facebook and Twitter dominating the web as such because I don't have any accounts with them: They are commercial entities filling a need. Capitalism at work I suppose." 1. It's not pure capitalism when there are political mechanisms in place to subsidize entire sectors of the economy and protect, through the arbitrary application of laws and regulations, some companies but no / at the expense of others. 2. Capitalism, on its own, by which I'm assuming you mean the market mechanism for price discovery and resource allocation, does not solve problems like the tragedy of the commons, it does not concern itself with things like civil rights or labor rights, it does not opporate satisfactorily in many sectors and circumstances such as building out public transportation before it is needed or financials panics or war time. 3. Neither whether or not you personally have a problem with them and whether nor not they are filling a commercial need are social issues. One is a personal issue. The other is a commercial issue. Perhaps you should consider the issue for a societal perspective.
