... Socialism is a process, a path toward an equitable classless society.

There have been many variations of what that path should look like, throughout the history of socialist movements.

'Minority share' is a funny way to refer to 'a 50% share'.

The phrase you are looking for is 'controlling interest', as nothing can happen in the board level that you do not approve.

If the stocks and companies go to zero... well the government took them by force, (thats what nationalizing is), costing them no money.

So the net loss is 0.

So again, you don't understand the words you are using.
