Southern France has wonderful weather and the Mediterranean Sea. The EU should start a special economic zone for startups there (a split of later taxes going into the EU budget).
Don't think it's particularly startup-friendly though.
He spends a good part of the book complaining about french research, which does not care about products impact and thus is very theoretical, but also about the heavy hand of the government in dictating where innovation happens.
He also talks about Sophia-Antipolis. It started with a boom, and a lot of tax credits to incentivize corporations. But after the subvention dried up, many companies left. It seems to me that most of the companies left do not have innovation in their DNA.
