The people en-masse being in control. Representative democracy, by it's nature, creates a "ruling class", the representatives. Only a direct democracy asks the people what they think of each and every issue, but that is impractical in my opinion.

No, that's just our government/s. You can have representative democracy where representatives are beholden to their constituents, and where they are easily recallable if they do not follow those interests to a T. This is one of the many reforms socialists want to make to the democratic process.

...and I don't feel that leaders of state owned capital are particularly any different from leaders of privately owned capital. Both are individuals in privileged positions of power that work to maintain themselves above the workers. To me it's not the ownership that matters but the fact you have a ruling class at all.

Genuinely no offense but this is a position born of ignorance. Under a democratically run state economy the representatives only get rich through corruption. Under capitalism the owners get rich through the extraction of surplus labor value and the politicians in their pockets get rich through corruption.

Corruption is a drop in the bucket compared to surplus labor value theft. Compare how wealthy Pelosi is to how wealthy Jeff Bezos or Elon musk are. And people like Pelosi are only that rich because of insider trading, which couldn't exist under socialism.
