I started to make a list of all the things you can get in 2013 that you couldn't get at any price in 1970 (notable ones included Gleevac and a Blu-ray set of the Godfather trilogy) but I am just going to give up. If you think you'd be happier living as the median American in 1970 than as the median American in 2013, especially in the Socratic satisfaction sense of knowing the experiences of both, I just can't imagine how to convince you otherwise.
