More Actualizible demand and so on, economically it's well proven through comparative economics.

I don't understand what the question means. We have welfare in the U.S.

We do in fact have a welfare nation, but it is not public welfare we have but rather corporate welfare. In essence, our government spends more subsidizing corporations than it does creating basic safety nets for the population. I think we can all agree that almost everyone in this nation should be afforded basic healthcare, job security, unemployment benefits, and an education, yet this hardly reflects the US' policy. Consider the pentagon. It is no secret that the US spends by far the most on defense, but what many don't know is that most pentagon officials don't ask for this gross overfunding. This money goes–for the most part–to corporations to conduct research and development on new technologies (a good deal of this money is mishandled and lost in the process, see the link to the article below for an example). This is quite beneficial to the upper and middle class who can afford the products these technologies yield such as computers and airplanes but not so much to the vast majority of Americans living below the poverty line.
