As the baby-boomer generation is the one born just after the war, we need to consider two things here: The parents of the baby-boomers lived through a war, and educated their children accordingly. And when the baby-boomers were young, and were forming their habits, many of today's luxuries weren't as common as today. Baby-boomer as young people did a lot less air travel than young people today, and they didn't get the latest iPhone every 2 years. Those things simply weren't invented yet, or were unaffordable to the general populace. Everyday life is a lot more luxurious in 2024 than it was in the 1970's, in terms of material possessions and things like entertainment possibilities. Baby-boomers had books, not Facebooks. On the other hand, house prices were at a lower multiple of average earnings. I don't think that baby-boomers are fundamentally different from other generations, they just grew up under different circumstances, and formed different habits as a result of those.

There also isn't a problem with the generation "dying rich". Macro-economically it doesn't make a big difference whether some pensioner is spending all his money, or leaves it to children who then spend it. What makes a difference is how within a generation the wealth is distributed. While there are definitively poor baby-boomers, the social and employment situation in the years where the baby-boomers were earning was less unequal than today. The wealth of the baby-boomer generation is better distributed than that of later generations. While the average millennial has less wealth at the age of 35 than previous generations, the top 10% of millennials have 20% more wealth than the top baby boomers at the same age. Graphs showing aggregate wealth of whole generations are misleading, as obviously both the number of people in each generation isn't the same, and age isn't the same. There is nothing surprising in somebody just around retirement age having more wealth after decades of work than somebody who just started earning. Millenials will be the richest generation in 2050, because the baby-boomers will be dead, and the younger generations won't have had the time to accumulate wealth.

I sometimes get the impression that there is an intentional effort to foster inter-generational economic jealousy in order to create a smoke and mirrors screen shielding us from the real problem. The real problem is economic inequality, and a diminishing part of the wealth created by capitalism going to the people who worked to create that wealth, while an increasing part is going to investors. Passive income is taxed lower than income from work, and wages haven't kept up with the growth of the economy. Higher minimum wages and higher taxes on dividends and capital gains would be the easiest solution. And that would also somewhat equalize the wealth between generations.
