You’re describing one group of bourgeoisie resisting a takeover by a different group of bourgeoisie. This is not a meaningful resistance to capitalism, this is the maintenance of a capitalist state.
Who are you talking about? AOC? If your definition of a democratic socialist is a left-leaning Democrat then it is thoroughly incompatible with mine, because I would require at a minimum that anybody classified as any kind of “socialist” be staunchly opposed to Capital.
IDK what country you’re from, but in America at least, a democratic socialist has about as much likelihood of being elected to any given office as a communist does, so if you’re looking for “realistic” policies you should look elsewhere.
Market forces on their own produce many if not all of the perverse incentives of capitalism. Only a centrally planned economy, built on a foundation of grassroots democracy, can hope to overcome those incentives by doing economic planning with an eye towards future sustainability and quality of life, rather than towards profitability.
