Couldn't we just ban tax evasion? What makes it so hard? (honest question) A recent European study has shown that the more company win money, the less they pay in taxes (in percentage). Is it because of bad laws? Corrupt politicians? Something else?
Europe is losing ~globalization and we are fighting over the scraps. Which European country do you think will be overall obviously better in ten years? And not in the sense that "everything gets better", but in the sense of having a high rate of success in converting progress to prosperity. I don't know of any.
You have to remember Western Europe has developed economies. They aren't likely to grow at the rate Asian countries are as those economies have a lot of catching up to do.
Also European countries don't necessarily have the same priorities as the US for example. Most of us prefer decent workers rights and consumer protections over 1/2% on GDP.
