Taxation is a different thing. Of those economies, only Germany can be considered successful by US standards, and Germany is an export-driven economy that sits pretty under the US security umbrella.
High taxation is not a model to be proud of. It is indicative of a lack of efficiency, IMO. Modeling the US after Europe is not exactly a good idea.
Well, what level of taxation would you consider to be high? Opinions on that will vary. As for efficiency, one could turn that around and say high taxation is required to counter the inefficiency of private markets in providing widespread prosperity, instead of concentrating it within a certain demographic. You do realize that social and economic mobility has been proven to be a fallacy, don't you? The old adage that you can achieve anything if you're smart enough and work hard enough, regardless of where you start from, is BS. We can all give examples of people who started with nothing, but became billionaires, but if you look at the statistics, people usually stay in the socioeconomic demographic they were born in. It's not all about stupid and lazy genes being passed down through the generations either. When wealthy people have greater control of a country's economic policy, it allows them to leverage their influence to their advantage.
Libertarians go on about equal opportunities, not equal outcomes. However, equal opportunities just don't exist "in the wild" unless they are fostered by an entity whose primary goal is to provide widespread prosperity, not concentrating it within the ranks of the wealthy.
This debate has occurred multiple times and it just seems to go in circles, so I don't think I'll add anything else to this one.
Getting back to the original topic of this thread, Huawei has launched a court challenge against the US government's ban against their equipment and China has now accused the two kidnapped (can we seriously call it anything else?) of spying, which is as vague as anything else they've claimed to date.
