The other comments currently here have pretty lofty (and I'd argue unrealistic) hopes for the future. I don't see any of those things happening. Let's be more realistic. Thing will stay generally the same. We'll be more tolerant of race and sexuality, but there will still be a ghost of those old feelings left behind - something everyone knows is there but can't exactly pinpoint. Societal pressures remain the same, but it's harder than it was before. With the push to get everyone into college, college isn't special anymore. A high school degree doesn't mean anything anymore, and a college degree doesn't get you much either. People specialize at a younger age because each field has become so expansive that it's impossible to give people a general knowledge about anything.
Natural fuel reserves start depleting. America, after years of burying its head in the sand, begins to invest heavily in alternative energies, but it's too little too late. Crippled by the lack of green energy, it falls from the mantle as the world's superpower as countries that had invested in green energy earlier such as Germany rise. America, in a desperate attempt to keep its industries going, beings more aggressive military actions to secure more fuel, alienating other countries.
People still remain the same though. They'll still squabble about small things. They'll still struggle with their own lives, the center of their own stories, knowing yet not comprehending how everyone is in the same place they are.
Poverty, hunger, violence - they all still exist. Everyone wants to live comfortably, and so they take more than their fair share of resources, just like they do today.
