i don't doubt that there are examples of this irl, but the reality is that most boomers aren't insanely wealthy, and the wealth they do have is tied up in their home, meaning they're really only a millionaire on paper and the only way to ever actually realise that wealth would be to sell up and move to some shithole area that is substantially cheaper. i'm not from a wealthy family but i grew up around a lot of wealth and from my experience wealthy parents do give a lot of assistance to their kids. it's typical in the circles i run in to have your parents pay for the entire down payment on your home, anywhere from $40k to $200k. i know two people in whose parents outright bought them a property in their mid 20s. one was a $800k apartment and the other was a $3 million house. it's also very typical in australia for grandparents to cover some or all of the private school fees of the kids. and that was true already a decade ago when school fees were between $20k and $30k a year. school fees are now over $45k a year, and that's just for day school. if you are boarding it's even higher.  so yeah i think some people get upset with their parents cause they see them living comfortably while they are struggling without realise that being comfortable doesn't mean you are rich, and unless you expect them to remortgage their house or dip substantially into their 401k there's really not much they can do about your $30k credit card debt.
