Yes, but they only exist as a last resort! FDR-style Social Democracy happened because the entire world had melted down and there was not only an active Communist state, but also recent attempted revolutions in other Western states (Germany most notably with Spain right after it go going), and militant labor.

Now, we are nowhere near the condiotions of the Depression, not even fucking close (and the refusal to acknowledge this is a big problem). Now, we just have a bunch of non-profit/media careerists and desperate, usually mentally ill, beggars who think that their cause is the most important thing in the world and you're a bigot if you don't immediately ask for exactly what they want (but have zero institutional power or mass support for)

Capitalists don't give social democratic reforms unless they absolutely have to. Claiming that the reforms are "inevitable" and negotiating surrender before you're even in trouble is fucking loser talk, you don't do that shit!
