A few things to remember
.. and regardless of country. Companies hate competition as it's bad for business. The goal is a monopoly and if they cannot succeed in that they will try mergers and cartels. Remember how Apple and Google and others agreed on not having to compete for people. Or how pissed off ISPs are if some community tries to deliver their own internet infrastructure.
The Intel/AMD case was a no-brainer and, as with Microsoft, one has to wonder (or perhaps not) why those American companies who complained turned to the EU and gave up regarding the US DoJ.
For more on thoughts about "Anti-competitive practices" try the Wiki:
Without laws and regulations regarding companies we end up with something like the old USSR.
As for income inequality our American friends have already surpassed the old USSR.
Lets not be too "blue eyed".
