It was this that set me off:
It would be nice if this actually led to a crackdown on tax evasion and like ills, but such things are in no way central to global capitalism. Much of the big money in these accounts doesn't even come from capitalism at all, but from government corruption in places like Russia and China. Unless you're one of those people who thinks that "capitalism" just means enriching the few at the expense of the many, in which case you don't know what you are talking about. We had the rich and the poor for thousands of years before we invented capitalism.
People like the author of that dismal screed I just cited think that these secret documents will expose something about capitalism that turns people against it, leading to electoral victories for Bernie Sanders and his pals. I suppose some people may find all this news about offshore companies and secret offshore bank accounts alarming, but so far as I can see the real evils of capitalism are right out in the open. The gargantuan salaries of CEOs are matters of public record, as are the tricks of legal tax evasion that allow companies like Apple to pile up billions in overseas bank accounts. Companies issue press released when they close plants in the US and move production to Mexico or China. Pollution was never a secret; the Cuyahoga River burned on national television.
Of course the failures of socialism are also matters of public record, from the destruction of the British automobile industry to Chernobyl.
Really we already know more than enough to evaluate the world's various political and economic systems and judge which we would like to live under. No secret file is going to change anything.
