The current capitalist system moves wealth from the poor to the rich. That sort of works, if the total wealth is growing at such a rate that the poor keep their quality of life. However when you have stagnation and even worse a decline in GDP you end up in a situation, where the poor get actually poorer and the rich either keep their wealth or become richer.
So with a stagnating economy, you have to change the system to stop the flow of wealth to the rich. When you want to actively shrink the economy, you need to take from the rich.
In this case these numpties work for Murdoch.
