The Republican Party is fully owned by Our Corporate Overlords.
But don't ever think that the Democrats are completely autonomous.
Donald Trump was not in the Oligarch's playbook, they expected(like everyone else) that Hillary Clinton would be delivering the goods behind the scenes right now rather than Trump's hamfisted economic policy. Clinton would have been far better for all concerned, rich and poor alike.
But as is almost always the case...the rich would get richer and the poor poorer.
We seriously need an adjustment where the rich gain a little less and the poor finally get a break. Even for just a little while.
