You didn't answer my point, you just changed the argument so you wouldn't have to deal with the reality that Finland, Denmark, Iceland, and Sweden are real countries with real outcomes, and not theory.
As someone already mentioned, your definition of Socialism is wrong. Socialism does not mean “the government owns everything.” It means social ownership of the means of production, which includes public ownership, worker ownership, cooperatives, and regulated markets. That’s from the Stanford Encyclopedia of Philosophy, not just opinion.
To bring up the fact they didn't have a revolution is evidence against your position. Socialism doesn't require revolution, that's a Marxist-Leninist subset. The Nordic countries put in strong socialist policies democratically, and they work.
Complaining about high taxes without looking at what they get in return is dishonest or you just really don't know (Universal healthcare, free education, childcare, great unemployment insurance, pensions). In general, the people there are happier, healthier, have more economic security, and more disposable income. That's just fact.
You said that welfare is “the first thing exploited”, which is flat-out wrong. Welfare fraud is miniscule. Corporate tax evasion, wage theft, and subsidies cost everyone insanely more money. Wage theft alone is more than ALL other forms of theft combined (US department of labor). Only difference is, capitalism rewards the greed whereas socialism policies exist to limit how much damage that greed can do.
Even when I said that the US was at its peak and had a strong middle class, that was due to their strong unions and regulations were enforced. So basically capitalism being restrained by socialist policies. They've been removing those policies, and now look where we are.
