The EC desires to get more and more power over EU countries' policy, with the excuse of "doing its job". In a normal country, the executive branch is also elected by the population. In the EU, they get there by appointment, so they are an extra step removed from democracy. It is just the opposite of what you want to do to improve democracy. Instead of more opportunities for people to control government, you're creating an extra level of indirection that makes control even harder.
