Publicly run industry doesn’t normally function with the same circuit of turning money into a larger sum of money that I described, nor are administrators a “ruling class.” Inequality in distribution exists, but isn’t necessarily the problem, equalitarians that seek equal distribution for everyone are exceedingly rare. There’s a qualitative difference in outcomes for the working classes in socialist countries where public ownership is the principle aspect that manifests in dramatic uplifting of their material conditions, whereas the point of the capitalist system is said inequality. The sheer scale of inequality in capitalist systems far surpasses socialist countries.

In the USSR, for example, the gap between the wealthiest, ie professors and scientists at the top and the average factory worker towards the bottom, was about ten times. In capitalist countries, that number skyrockets to billions. In the PRC, which has a socialist market economy, the number of billionaires is going down while the GDP and GDP per capita of the PRC is growing dramatically year over year, alongside real wages.
