It takes more than this. Without the right attitude most people will just party or do what everyone else does to get by rather than work towards improving themselves and their environment . Do the methods used to provide for peoples basic needs encourage them to be curious and productive? If not, then it may not be worth it.
Well then the science disagrees with what I observe in my every day life. Also, I didn't say you did posit a method, I was just putting the issue forth as something to be considered. Dismissing what I said because it has been "scientifically disproven" would be unwise.
"Science" is wrong more than right. I have a degree in psych, I think it is mostly people arguing about various opinions (slightly better than "philosophy"). The field is valuable in that it provides phenomena to be explained by the more "bottom-up" approaches, but I wouldn't take the aspects of it that make it into pop culture that seriously. Using the psych literature as the basis for public policy is foolish. Sure, use the information, but don't treat it as some kind of infallible truth.
