no i think "Caricature" works fine. Boomers are grotesquely greedy and materialistic and are even
refusing to leave an Inheritance to their children when they die. if you described this generation to anyone else in history they'd think you were joking. As a group they are like an exaggerated strawman conjured in the mind of a retarded reddit communist to decry the Evils of capitalism but they're real.
Millennials are just as greedy and materialistic but largely that's a consequence of the boomers teachings and the main difference is they have no wealth to horde. they don't own homes, they're being crushed with debt, many can't afford to put money in the stock market or invest in anything, there are hardly any good jobs that can support a family on a single and boomers are refusing to leave any inheritance at all. They sell their homes to BlackRock, move into lavish retirement communities and take cruises and European vacations, to squander everything they were given before they go as a final "Fuck You" to their children and grandchildren.
