In real terms, will religion eventually fade from America?

I think that within the next 50 years America will either not exist, or will be the secular nation that it should be. I honestly have low hopes for both of these things. If America legalizes Marijuana we will be a tourist country even more than we are now. If we stop doing statewide laws and have the federal gov comply with the popular voters and we do all federal funding,,, including healthcare we can succeed. We must rid ourselves of capitalist views and see the people as a group rather that 4 groups, high class, upper middle, middle, and low class. Then of course the sub low class living in housing projects. This country needs some restruction before it will ever be in power again. Just look at the health and education standards compared to other countries. Im sorry for ranting
