again: i'm not an economic populist, i'm more of an mmt/keynesian type. so, i'm not going to approach trump's tax policies through some filter of mid-twentieth century wild west progressivism, which seems to be the standard reaction on the pseudo-left, nowadays.
the reality is that the united states doesn't need to have taxes at all. it could just print the money it needs. so, it's less that i'm in favour of this or opposed to this and more that i realize that it doesn't actually matter.
will it do any of the things that trump claims? no.
will the united states collapse in some right-wing snuff fantasy of debt porn? no.
will some rich people get to sit on some money that they ought to be spending? yes.
what would i do, if i were the empress? i would take the money out of accounts and spend it. that's what the left is supposed to be about with fiscal policy: we're supposed to be about advocating increased levels of spending.
so, i look at what trudeau is doing and he's getting it wrong: he's taking money away from the right people, but he's not spending it. then, i look at what trump is doing, and he's getting it wrong, too: he's giving spending money to people that don't need it.
but - and i stated this previously - it is actually, in theory, less bad to let the money collect interest than it is to take it out of circulation.
i would advise the democrats to kind of shrug this off, and even try and use it for leverage. if i were a senator, i'd be willing to support tax cuts like this in exchange for increased spending, which in the united states would be mostly about infrastructure.
what's important is not that revenue stays high (that does not matter in a fiat monetary system), but that expenditures remain high. and, the way to get the economy moving is to get the state to spend more - regardless of how much it is taking in. that is what people should be focusing on...
