Why are people complaining about this? It's not even that high of an amount compared to several other developed nations. It's not a recent trend either. It's been going on for over 30 years. No one here seems to care about the objective number (40 million) - they instead care about the relative amount (29%). If you look at the graph and track the percent, it's been at or over 25% since 1990. Having your share go from 25% to 29% in 35 years is not really that meaningful. This isn't a new phenomenon in the US. The graph sucks because it hides the fact that the US population has been growing steadily.
