America: How long will we remain capitalist?

In our ever changing world, cultures and ideals change as the peoples needs become different. Currently the United States is extremely materialistic and lives to work. It seem our only goal in life is to buy flashy items to somehow show off to the people we interact with daily, but there's something that isn't working, we're becoming a very sad nation. Happiness can be a very powerful emotion and the people in Europe have been finding this more important than possessing objects. Within the near future the United States will hit the threshold and we will change from a live to work nation to a work to live. Take a look at Finland or Denmark. Do you think there's a reason they're some of the happiest country on earth? They don't have to worry about a declining infrastructure, or about going bankrupt because of a greedy medical system. When Americans realized taxes can be a good thing and spending the extra money on good and services produced and provided by their own country then we can finally make a step in the positive direction.
