The interesting thing about the article is that all this EU regulatory control over corporations is in fact deeply capitalistic and the very reason for its existence, and in the corporations interest. Which is not what most EU citizens would consider being on the left of the political spectrum.
The idea is: we need regulation to shape the market where businesses can compete freely to the advantage of both businesses and consumers. If we don't regulate, monopolistic corporation would threaten the single EU market.
Or even more simplified: we need rules to have a free market. The US version (or one of the versions) of capitalism is more of a free-for-all, where the most important thing is to reduce regulation, not increase it. It seems to trust the judicial system more than the government.
