A “capitalist,” according to socialists, esp. Marxists, is someone who engages in anticompetitive behavior, insider trading, protection racketeering, bribery, and all manner of dubious and criminal behavior.
No, a capitalist is someone that owns the means of production and doesn’t have to work to live. People like Jeff Bezos, Elon Musk and Mark Zuckerberg. And since capitalism is an infinite for profit driven economy, the capitalists will do anything to increase their profit and their power, hence why they engage in the things you listed, the system literally demands it.
Someone who just believes that people should be able to trade freely, associate freely, and keep the vast majority of what they have earned or traded for fairly are routinely called capitalists by socialists and communists to shame them for being successful.
No, we call them liberals or neoliberals, because that’s what they are, “capitalist” have an actual definition, like I explained above, just like what you are describing is a lib. Besides, everyone can trade freely in a socialist society, what they can’t is own the means of production and exploit peoples labor for their own profit.
Also, we don’t shame people for being “successful”. There is no moral judgment, we simply understand how the system work and want to dismantle it, so exploitation from human being to human being ceases being a thing.
If the worker makes everything, everything belongs to the worker and not the 1% at the top that does nothing.
