As for age, it is not just the cost, but also the alienation of the young from messy analog physical dexterity, long low stimulus attention and slow progress in favor of high stimulus instant digital gratification.
I think the real problem is that y'all got houses to put a train set in for like $3.50 and the only people I know with houses are the ones who's parents put the money down and cosigned the loan. The models fit on a shelf in a tiny apartment with a roommate.
Maybe vote to approve some apartment blocks and public transit next time around?
Since I moved out of my moms place I could not bring my 3d printers, cnc machine or electronics equipment. I simply cant fit it in this tiny apartment with my wife.
I have lost these hobbies over the past two years to software entirely. Not necessarily a bad thing.
I guess my point is, you can lose your slower hobbies without even realizing, just due to circumstance. It's not necessarily the younger generation's "fault". It is often just the emergent consequence of the situation.
I suggest any boomers with this attitude check out what the kids are doing with Gunpla and Warhammer. It's a space issue, not a "stimulus" or "physical dexterity" one.
That being said, the same place I buy my monster and spaceship painting equipment from seems to still do a decent trade in benders and slips.
And size is still an issue, the smallest ship I could build is about the size of the largest "miniature" I have.
How many times did boomers look at the two buttons before them, "make housing affordable" and "make housing a good investment," and which button did they press every singe time?
