Well Socialism and Communism are two very different things. However Communism, in the sense of a country moving towards Communism, rather than being Communist, often has Socialism (with a capital S)
Socialism is about government control of industry.
Communism is about common ownership, as opposed to government ownership. It is classless, stateless and moneyless. So, you don't have strong leaders like Stalin, Xi, Castro etc. It's something of a contradiction between those who claim to moving towards Communism and Communism itself.
Socialism can have classes, it did in the USSR, Warsaw Pact countries, China (barely Communist if not at all right now) actually has more of a class system now than it did 40 years ago when most people were poor.
Certainly they all have money, they all have states with strong leaders...
Any evidence that Kamala wants a stateless, moneyless, classless society?
