As everyone knows, the country is going to undergo some significant "graying" over the next few decades with the proportion of senior citizens going up substantial. That's going to pose a challenge on many levels, but one level is that building more and better transit will help us cope with the problem that seniors often aren't comfortable driving, especially in sub-optimal conditions, and it often isn't safe to have them on the road. If we don't want to see a huge proportion of the population immobilized, we're going to need more ways for people to get around.
The US is particularly miserable at putting aside money for the future. Should we blame our paychecks or our psychology?
