Boomers had it easiest financially by a very long way compared to the generations that came after them. That's not an opinion but an easily proven economic fact; higher salaries, much easier job entry requirements, property prices, a lack of college expenses and need, and so forth made it massively easier. The inflation of past periods is absolutely insignificant in comparison; even at the height of it at ~14%, that's barely on par with what younger generations already face in rent prices and salary pressure among other things. https://twitter.com/graykimbrough/status/1198703644721524744
In addition, while jobless numbers were high at the high point of inflation (~10%) back then, today's job numbers count zero-hours jobs and other jobs that don't actually make people a living, which account for quite a bit. That's on top of many younger people having to pay student loans with that which have pretty high interest rates in the US.
As for NFTs, there's actually a comparatively small number of people with money to invest in them: most NFTs are owned by a small group of around 10-15% of buyers. Many of those are people who inherited generational wealth, though of course that isn't all of them; boomers hold the vast majority of wealth right now (in property, mostly).
Unfortunately the rich people in the NFT space know full well that NFTs are a terrible idea and a ponzi scheme of sorts at best, but they know they can profit from making uninformed people buy into it. As you say, it will end badly for many people, and people who are not involved are suffering already; crypto speculation is messing up markets, affecting GPU availability, causing power shortages around the world and more.
