I thought that this 'alliance' was called ownership. Rupert Murdoch et al whose political agenda is less government control and more control for the private sector which translates into private control by fewer (and fewer) people with less accountability. Essentially what we are going through, world wide, is a consolidation of wealth and power into fewer and fewer hands.
This consolidation suites the purposes of the ownership of media companies, and it is the media companies that set the tone and content of their reporting. Over the last 50 years there has been a massive consolidation in the ownership of media companies, with a corresponding massive shift to a very right wing perspective in popular reporting.
I can not think of a single time that a strike by a Union has been reported in a favorable light, for example.
