For pretty much all of my adult life I have seen generational warfare afoot in this country, but never on the level of Trumpism. Trumpism is white baby boomer generational warfare at its most acute, as Trump's recent budget proposal proves.
This budget would add tens of billions of dollars to the defense budget, a military buildup likely to lead to a war (they always do) where the youth of America will be sacrificed. At the same time, social and environmental spending will be slashed, while Social Security and Medicare will remain untouched. The elderly white middle class will thus retain their entitlements and be protected unto their deaths, which will likely happen before the effects of mass pollution take hold for everybody else.
The aging white population came out for Trump in a big way. They are basically fine with making everyone else suffer as long as they are protected. Back in the 1980s, Reagan had also figured this out. He too sheltered Medicare and Social Security while slashing away the parts of the safety net that helped the young and poor. Reagan was a shrewd enough politician to know that his free market hocus pocus didn't wash with the great masses. He also knew that middle class white people would support him if they knew that other people were getting nailed harder than they were. It's a tale as old as time in this country, my friends.
Those of us below a certain age will likely find out that the tiller is empty when we come to collect our retirement. In the meanwhile we'll be breathing polluted air and watching the thermometers rise. That's been par for the course for the older generation, of course. They grew up with a robustly supported education system that made it cheap to attend public universities. At the same time, they could get good jobs still without higher education. Then, once they reached adulthood, they decided they'd rather not pay the taxes their parents did, and made public universities insanely expensive right as they became more essential for entry into the middle class. They were the first generation and in fact the only generation to benefit from the post-New Deal state from the cradle to the grave.
The generational war is over now, and those of us not fortunate enough to be on the winning side are going to have to face a bitter defeat who consequences still can't be foreseen.
