Exactly. Democrats won't fix that principle; they may (eventually, maybe, years into the future) raise minimum wages, which would be helpful for a while, but they cannot stop capitalism being capitalism.

And, dependent on capitalist donors just like Republicans, they won't be able to take radical action against the status quo.

This is what many blame the failure of Biden administration to make economic reforms on - Democrats, too, play under the rule of the market, just less openly than Republicans, which is why they always try to find scapegoats to sabotage the most radical plans even when they take the majority of seats.

That's not to say you should vote A or B. That's just to mention that Democrats are not your friends and saviors, and they can only be seen as a lesser evil until people organize, come out on the streets and demand loud and proud what they deserve. They have nothing to lose but shackles.
