And Munich is the most expensive city in Germany.
That's not to say that all parts of Europe are better to live in than all parts of the US; but rich, central urban areas of the kind that techies can afford to live in are fantastic in Western Europe.
Once you get past that - i.e. accept that you'd have to drive - the density of services is fine, they are pretty much same distance (measured in time) you'd find them in the city, except that you're driving there.
As for return on your tax dollars, can't compare to Europe due to lack of information. Healthcare is fine, retirement savings don't have much to do with tax dollars anyway.
Another issue though is traffic during rush hour in Silicon Valley. I can see myself traveling 20 miles in/around Munich in half an hour, while in Silicon Valley, that would probably take me 1.5 hours, because of the pretty much non existent public transportation.

SV seems like the place to be, but I lived in a cheap french city for the past 5 years, and I'm sure living in SV has its downsides in terms of quality of life. Bonus: please include numbers :).
However, I decided to go back to San Francisco. There is definitely much more interesting work in Silicon Valley, at least in my field. This may change over time but I am not holding my breath.
Very early stage startups might be able to move around Europe for a short period for cheap rents, you're going to be much less able to recruit staff (i.e. non-founders) to move from the West to Slovakia (as mentioned) to work for Slovakian wages.
