I guess there is this strange notion that Capitalism is this "all or nothing" system, where you either get a free market with its invisible hand or nothing. This sort of "Everything else is communism" thinking.
We all know that this is not true. Capitalist societies have all sorts of schemes that are "un-capitalistic". Take public healthcare. In some ways that's a very socialist idea. At the same time, you could argue it supports the capitalist system by taking various burdens off the workforce, enabling them to spend more time generating more money than it cost to implement the socialist health care.
My theory is that concentration of wealth is incredibly dangerous to society because it gives disproportionate power to very few individuals. The control these people exert over policy, their workers, our entire culture leaves us at their whim. This results in things like Brexit and the insane clusterfuck that's the current US government and the populist right-wing uprising in Europe.
I don't care whether someone has tons of money so they can wank themselves to sleep over their financial portfolio. I do care when society as a whole, human progress, everyone's actions are filtered through the lens of a few rich people's actions and desires.
I hate this notion that the population-at-large is just a sideshow on this rich-people's playground we call earth. It is sickening. The wealth that these people amass does not trickle down and is not used for more useful things than it would be if this wealth was somehow capped and re-distributed for the benefit of society. (And believe me, I know that on the flipside this would be a breeding ground for bloated institution wasting money with their inefficiency. This would also not be a 'perfect' system by any means, but I do believe it would be better than whatever it is we are currently steering towards.)
To quickly touch on people being lifted out of poverty. I am all for it. But under what conditions? Is a Foxconn factory worker someone who was lifted out of poverty? Is a quasi-slave working on the Qatari football stadium lifted out of poverty? In exchange for what?
Is the ever-decreasing quality of life people on disability benefits in the UK, being harassed by the DWP 24/7 and stripped of all agency and freedom worth it, because they are not considered "below the red line poor"?
Would the reinvigoration of public services by capping wealth (or introducing profit sharing in companies, or 20:1 pay ratios / stock option ratios for companies) be so devastating to all of society that it would indeed be worse than the current destruction of democracy by your Murdochs, Kochs, Zuckerbergs, Bezoses, Rothchilds and whomever else super-rich acting in their own interests?
