Michael Roberts, card-carrying Marxist economist, evaluates MMT: “MMT only offers a backstop to capitalist investment and employment, not an alternative.”
This does not excite the MMT philosopher Tom Hickey: “OK. Well, MMT didn’t set out to replace capitalism. So, the MMT economists are not calling for revolution. As if that is most serious charge that can be mounted against MMT?”
No, the most serious charge against MMT is that it claims to benefit WeThePeople but instead benefits the Oligarchy. To pay for social benefits with deficit-spending/money-creation is simply a political fraud. This is because of the macroeconomic Profit Law which boils down to Public Deficit = Private Profit. So, MMT offers a permanent free lunch to the Oligarchy which is beefed up with interest on a permanently rolled over growing public debt. This amounts to reversed taxation of WeThePeople by the IRS on behalf of the Oligarchy.
Fabulous wealth in the USA is the mirror image of fabulous public debt (~$22 trillion) ― NOT of productivity, innovation, monopoly, free markets, or exploitation.
Because the Marxist economist Michael Roberts does not know what profit is, he swallows MMT as an employment program and does not realize that it is a profit program that keeps the Oligarchy alive and well until the growth of public debt hits a wall.
Two hundred years ago, Marx did not understand how capitalism works but things have not improved in the meantime among Marxist and non-Marxist economists.

You ask: “How to analyse the current impacts of deficit spending to prove MMT does not and will not work to rescue capitalism in its current form?”
MMT does exactly that because deficit-spending/money-creation is a free-lunch for the Oligarchy, see Keynes, Lerner, MMT, Trump and exploding profit.
