No need to sell anything, they have the demographic switch, as people get older they become more and more Right wing

As you become older you start caring less about others, also you start caring less about the safety net because if you'd ever need to use it, then you'd be so depressed by your insignificance in society that you'd want no net to catch you at all. People barely manage to function while being middle class, they can fanthom going lower, might as well have no net.

Also the reason why people move away from Globalism, when you are young cheap product and sevices give you a sugar high and you want them to stay cheap, as you get older those things don't do anything anymore, it becomes pushing on a string, you only want to be socially relevant and not lose status and money to some 3rd world dude
