"ism" words get defined for political purposes. And the overwhelming success of regulated capitalism over the past century has moved the definitions of socialism and capitalism in toward the middle, because the extremes are no longer politically tenable.
For example, socialism, to many of its proponents in 2019, means using the collective power of the government to tax the rich in order to purchase better outcomes for all citizens--even if those purchases are from private parties. Lots of people are in favor of "single payer" government health insurance... not nearly as many folks are saying let's force all doctors to work only for the government. That's what socialism meant 100 years ago. But that's not what socialism means today to most folks in the U.S.
Likewise, the popular understanding of "ending capitalism" in 2019 mean ending the political, regulatory, and tax regimes that enable complex financial engineering that results in huge paydays for Wall Street and tax avoidance for rich people and big companies. "Capitalism" in this sense is not intended to be a technical term referencing property ownership rights... the word is being more like the name of belief system or set of values--one that doesn't care about income inequality and poor people.
"Socialism vs capitalism" for most people in 2019 is really a fight over values and political priorities. The words are placeholders for systems of belief. It's not a fight about private property rights in general like it was 100 years ago. I mean, maybe it is to a few people, but not many, relatively speaking.
That is, lots of people are fighting about extracting wealth from rich people and huge companies... not many are fighting to end their own right to own any property, to surrender it all to the government.
