I can only speak for the UK (and lumping all of Europe together is pretty foolish given that it has a range of countries from borderline 3rd world to international superpowers) but in London the tech scene is very much alive and well. I myself work for a middle aged startup (going through some horrible growing pains just now), I love to get involved in the London tech scene and I've talked with plenty of people doing well from startups.
PS: Per person the US government spends as much on healthcare as many countries with 'national' healthcare so we are paying for it even if we don't have universal healthcare.

PS: As a sanity check. Federal (24.33 GDP -3.72%GDP given to the sates) State spending is 8.97% of GDP, local 10.69%, which adds up to 40.27% GDP. Note: Actual revenue is only 32.61% GDP because we are just borrowing that much money but debt does get paid back one way or another. http://www.usgovernmentrevenue.com/year_revenue_2012USpn_13p...
What? Citation needed? In some countries they give money to startups, not the other way around.
And how you you explain "high tax rates" when Barack Obama refers to some countries in the EU as a tax haven?
