Nice article. Of course, you could write a book on this. But I think the elements you picked were good ones.
I agree with some of the other comments. The changes in the way people lived from 100 BC to 1776 were far less dramatic than the changes and advances that had taken place from 1776 to 1966. Although there has been some continued advancement, particularly in computers, and there is more to come, particularly in genetics, it has not been at the pace of the time leading up to the 1960s. My father, alive and 93, used to run after cars that drove up his street when he was a kid because they were odd, and yell, "Get a horse." His mother who was still working in the 1960s, was born before the flight at Kitty Hawk. The rapid advancements witnessed by those generations left people feeling anything was possible. And the idea of community, society and common good had not been denigrated to being "Socialism" or "Communism" unless you did it through a religious organization. Government wasn't per se 'the problem, not the solution.' A firefighter who worked for the government wasn't suspect if he came to help you put out a fire. I like to point out that the US put about 1 per cent of it's total GNP into the space program in the 1960s, and you didn't have somebody yelling 'waste, fraud, and abuse' every time they tried to create a technology which didn't pan out.
Using Wikipedia, the economy of the US in 2012 was roughly $15.7 trillion. If NASA was given 1 per cent of that, it would be $157 billion. It's actual budget was 17.7 billion, a little over 1/10 of that.
