That's a different topic with various factors involved... But generally pricing someone out can keep a competitor off shelves. Most companies want to secure marketshare.
This is not the same as what happened during covid, which effected the whole of the domestic market at once. Obviously tariffs on specific importants is a different effect than that.
OP how much of today's markets and politics are definited by Oligarchs and the rich? Can you really say that a plutocracy isn't it's own kind of dictatorship?
Even more so, many westerners have been fooled by culture to think this is natural, inevitable, and good.
In terms of per capita rates, the Irish Catholic Church was incarcerating more of Irelands population than Stalin did to Russia during his reign.
Just two companies; The British East India company and the Belgian Rubber plantations of the Congo killed more people than Stalin or Mao (especially if you factor out the deaths from Lysenkoism, which wasn't a part of communism).
So early Capitalism and Colonialism killed far more than Communist dictatorships have....
And finally there is this to say - Communism is an economic system designed to interrupt plutocratic rule. It's not a governmental system of elections and checls and balances....
...and if we are to be the most up to date with this: China and Vietnam have Socialist Oriented Market Economies. The one in Vietnam, has almost eliminated homelessness entirely. Is that a dictatorship compared to the woes of the west's housing crisises?
Early systems from both economic models - Capitalism/Colonialism and Communism - both had events of mass killings. Both have seen dictatorships... You only focus on these things in the Communist model, because of your background. Likewise, someone from China or North Korea might hear more about the famines, deaths and genocides of the Capitalist and Colonial corporations I've mentioned above.
P.S. Are Cancer deaths from chemicals Capitalists kept on the "safe" list indicative of a dictatorship by the wealthy? What about the deaths and famines from weather disturbances in the climate? If we're counting the famines under Communism, then why not these things to? It's because of a hidden Western ideology/indoctrination culture.
