Which regulations have "resulted in low investment and slow innovation"?
Not regulations, incompatible regulations. If you create a startup in SV, you can easily sell to the whole US. In the EU, you’ll need to obey 28 different laws, 28 different standards, and file 28 different tax forms. This is currently the single biggest hurdle for startups in the EU. The second, of course, is that people seem less willing to throw billions at risky concepts just so one maybe gets big enough.
Different social attitudes to risk, and a language barrier, are no doubt much more pressing concerns.
