... But like all loopy socialists, sooner or later, they run out of other people's money. ...
Seems like projection, because the Right wants war after war after war, while not wanting to pay a penny to finance those wars. As AOC notes, we always seem to be able to find the money to pay for "unliimited war".
Also, if AOC were more outspoken about her socialism, she would explain how it's not "other people's money". Money is just the tangible, exchangeable form of the value we place on goods and services, and all of that value is the product of labor. Taxing the rich to pay for social services is
taking back the money that should have been in the hands of the workers they exploit and (ideally) using it to further the interests of the workers themselves. Of course, when this is enacted by states that are intertwined with capital, the social services most often further the interests of capital first, with any benefit to workers being a side effect.
