Want to go and read those books? No? I’m schocked.
The information from those books is listed on Wikipedia, yes. Are you so childish that you’ll now pretend “you can’t find real information on wikipedia”?
Weirdly enough, you don’t have ANY sources for the things you pull out of your arse. Almost as if you didn’t know what you were talking about and didn’t HAVE any sources for your faulty claims, because like I said, you’ve conflated market economies and capitalism and think socialism equals communism, because you don’t understand communism is just one form of socialism.
“How can you have socialism with capitalism”
Since I’ve already explained you keep conflating “capitalism” with “market economies”, the question is then translated into “tell me, plainly, how can you have socialism and market economies”, for which the answer is really quite simple for anyone literate. However, since you also conflate “socialism” with “communism”, then the question becomes “how can you have communism with market economies”, to which the answer is “you can’t, since communism relies on planned economies instead of market economies”.
That’s where your confusion comes from.
Due to our good regulations because of our social demoractic, well governed economies, capitalist companies can participate, but they can’t do the shenanigans they can do in less regulated markets. The degree of regulation is the question. Even the US doesn’t have “pure” capitalism. Things like the antitrust laws are by definition socialist policies, but this doesn’t mean the US is socialist in any way. It just means even they understand the necessity of regulation over “pure” capitalism, because “pure” capitalism is unsustainable as it leads to monopolies which then kill the economy.
This is why for example I can actually drink my tapwater and eat raw eggs that don’t even have to be refrigerated. This is why the quality of all products here is higher, and why it’s more expensive for companies like Nestle to try their bullshit here, which is why they mostly aim for developing countries. To avoid the regulation that comes with properly functioning social democracy.
