A rich person would have most of their assets invested, existing in the form of factory equipment, buildingsin active use, truck fleets, etc. That is, pretty much moving.

Only if they're so inclined and even only part (they'll keep large parts in less risky form, including land etc -- also not sure how "investing" in "buildings in active use" is not rentierism and how it helps the economy. Whereas the middle/working class have no other option but to put the majority of their income directly in the economy again (buy things to live).
And that's not even taking into account the fact that the rich could very well invest elsewhere, or hide their money in tax havens, invest in foreign housing markets, and such, in which case the society they live in, and which they make their money, gets zilch of those money. Again, not the case for middle/working class people.
But assuming that the rich did invest most of their money, that would still have the problem of the rich calling the shots (through their investments and wealth), which is less of a problem in a less unequal society.
