You must understand, that's like asking me to write a book. Its really that complicated (As I see the issue anyway).

Obviously I could get into detail, but frankly I don't have the time right now and maybe I could provide a more adequate response for this on the weekend. But in general terms (very general), it would help us have a sense of balance as to where true competition in the market place is ensured while human and workers' rights wouldn't be violated. Essentially, socialism (democratic socialism anyway) is here to say that "the freer the market the freer the people" is a significatly faulty point of view, in that the freer the market means the more freedom employers have to be in positions of tyranny in the lives of average people. This is why we have certain anti-trust laws as well as a number of other workers' rights and environment protection laws; to help gain some balance. But socialists want to take some of those steps somewhat further considering many do not work adequately or that we are behind in international environmental standards (for instance, we can't sell most of our cars to Chinese now because they don't meet even Chinese environment standards).

Also, Martin Luther King, Jr. sums up the main ideology of socialism pretty good for how short it is in a good quote, which the main part of it is in my signature.
