However this is a long story which cannot be discussed in here. There are many issues, when we say economy, that's a general term includes many items. For a developed economy like US, 4% is so high, consider this simple equition: Almost 11000 trillion $ is the total size of US economy, consider they adding 4% to that annually! I don't want to talk about the way that this wealth is being distribiuted but this is great. Whoever is elected, there still will be unemployment.
