That depends on if you believe in Stalin's ideas of a vanguard or Trotskys ideas of a vanguard. According to Trotsky the vanguard of the workers should be democratically elected.
Theoretically, amendments could be passed to alter the Constitution into anything, if they have support from enough states. Then again, if (theoretically) enough people support a radical change that is prevented because of the outsized influence of some states, how is that democratic?
No, if enough people vote for socialist candidates and they pass a law that says all property now belongs to the state, then it'd be enforced just like any other current law.
The transition could be gradual. If we started nationalizing companies that get too big, and do that for a few generations then the state would own 99% of the economy.
If we keep raising property tax, you'd effectively get to the point where people are leasing the land rather than owning it.
Communism brain rot is trendy nowadays. It’s the last refuge for the tortured mind of the permanently online doomers. It’s almost non existent in real life thankfully
that usually ends in disaster. never mind the fact that authoritarian governments like the power and wouldn't want to give it back, which defeats the entire point of socialism...
but even if you have a completely benign dictator (usually just a fantasy but for the sake of argument let's say we had one) people, especially in democracies, don't like the idea of a coup, unless it's them doing it but then it's a revolution. but that could also lead to reactionary sentiment.
we've seen this happen in Iran. democracy gets fucked with by a US coup, people react with a revolution but unfortunately reactionary forces use the anger to their advantage and devolve into a different kind of authoritarian regime anyway.
