Samuelson, Friedman, et.al. the rah rah boys for laissez faire capitalism, will always leave out that most crucial part yardman.  Not only are a very few picking up the bulk of supposedly normal gains they create the downturns that impoverish the rest of us by reaching into the investment pot periodically to take out enough to crash things, bemoan the horrible business regulations that "eliminated" so much wealth (as if money just disappears without a trace), stash the cash out of tax range or buy up stock at bargain prices, then expect the taxpayer to bail them out while promising to trickle down a bit for us to salivate over but never do.
All of this as if there won't be a reckoning at some point.  If not a global uprising then a final theft that the world economy can't recover from and which leaves the wealthy with no way to replenish their holdings or even have much to consume.  The snake eating it's own tail.  I guess they figure on moving off-planet?  Now would be good.
