I agree that while MMT presents as 'descriptive', to assume that human nature does not imbue descriptions with personally relevant meaning is to misunderstand human behavior.
It's actually quite simple to describe this without any judgement or subjective/political leanings. (It may be debated whether or not #systems philosophy is itself an ideology..)
The part where mmt shows taxes to be a dead-end in the financial flow, until spent back into the economy can be simplified/generalized further. Any system with flow will have the same set of logical parts that controls its physics. You need to know the volume that's moving, which includes both the velocity and size of the medium (like pipes & wires) it moves through the subsystems.
"Rich money" and "poor money" do not spend the same in an economy because of the important differences in their flows. Both taxes and profits inflate/increase the totals moving through the system, but to different areas. Profits flow up into the hands of the wealthy, and then 'trickle down' to the economy again (maybe, someday). It's very unidirectional, and most goes laterally to other wealthy nodes.
Taxing profits is *more* important than taxing incomes for this reason, otherwise, it's dead-end value for the system as a whole.
