I can tell you that I would not set foot in a country with high taxes. The US has some special incentives which even nowadays make it attractive (honestly, the US is so rich, big and special that the tax rate does not matter too much in the grand total), but in general, as a European there is no need for me to accept anything more than 25% when starting out. Everyone who starts out wants to keep their money. Especially starters need low taxes so they can invest more (and not only in the present year to get "deductions").
