LYAO as you like. I'm 60, and I went to uni at 18. Bought a house when DH and I were 27 and didn't have children until our 30s. The only 'benefit' we had as 'boomers' was student grants. We bought our first house with 100% mortgage on DH's salary of £12k because I didn't have a job after moving out of London. We had nearly bought a flat in London, over £80k. Thanks be we didn't, because that was just before interest rates soared to 15%.
I have always loved having my kids at home, though enabled them to spread their wings at the same time. All in their 20s now. Loved it in lockdown. Elder two have spent 4 years each living away from home. Both back - one, professional job, saving to buy a house, paying us peanuts. 2nd, degree educated, saving to do a further qualification abroad. 3rd in uni locally. Neither 2nd or 3rd expected to hand over any money but expect them to do chores/stuff like painting around the house. Much resistance.
They use my stuff, drive my car (though eldest has their own, it's been broken down for weeks, in for repair), lie all over my sofa, watch my TV, leave stuff lying around. Have to be asked to do chores. They are good kids, and I am so proud of them all but they seem to have reverted to being teenagers!! They do their own laundry and cook for themselves because I refuse to.
I love them dearly but this wasn't what I signed up for!
It's the same all around where we live. The bloody street is full of cars because none of the kids have moved out!! Any who did, have moved back!
I don't think they're useless, selfish or entitled. Mine are all focussed and know what they want in life, and work hard to achieve it. I just think the way society is right now doesn't allow them to live the lives my generation did.
