In Sweden you can more or less fire anyone as long as you're a small company, without any long notice. I don't recognize the other negative comments either. Taxes are high, but VAT doesn't matter at all unless you're a B2C company (and really it's the consumer paying for it, not you). Vacation is 5 weeks which I realize is a lot compared to the US (I've worked in US so know how it works). But if those extra 3 weeks are what kills your company?
Tax on salaries are quite high, but salaries are significantly lower (especially compared to the level of competence you get - but it varies).
On the other hand we have free health care (with a quality level similar to the top 20-50% level you get in the US is I'm not mistaken) and great support systems should you fail or something happens.
Admin is not obscene and you actually get a lot of help should you need it from the government agencies like the tax authorities.
Then Sweden has a similar level of entrepreneurship per capita as California or the SF region even I believe.
Access to capital do suck compared to the US (based on my limited perspective).
Fear of getting sued for silly shit is unheard of here compared to the US.
TLDR; It varies a lot between countries in the EU. It can be problematic to be overly generalistic in your description. It's for sure different, but I'm not sure everything just sucks compared to the US.
