Once a socialist government takes control of everyone’s economic livelihood, it will cease being democratic. It was the thesis of Hayek’s “road to serfdom” and it’s been the case in every truly socialist nation. Those who spoke out against the ruling party in the USSR were forced into less desirable jobs and housing, if they were lucky enough to avoid the gulag.
People will not give up private ownership voluntarily. The only realistic path to socialism is through a coercive abolition of private property. To do that you need a government with the power to enforce your prohibition. Once that state exists, the people in power will have every incentive to continue its existence.
