I have kids in their mid-late 20's. Expenses for them are so much higher than they were for DH and I when we were their ages. Apartments are expensive......unless they are dumps in a bad part of town. Then there's utilities/internet/computers/cell phones/health and auto insurance, etc., etc. Oh.....then there's paying back student loans.
Are your kids in their 20's-30's having trouble making it completely on their own? My kids are working themselves silly......but still, not enough money to cover everything.
Sometimes DD doesn't have much to eat. She does live alone, so that's a bigger expense than if she had a roommate.
I was pretty financially independent in my early 20's.........but back then, a used car was really cheap. I lived in $80/mo apartments. Life was so much simpler and cheaper then!
And it seemed like everywhere I worked, I got incredibly good medical insurance.
It's a struggle today, for sure.
