It's easy to condemn younger generations as lazy entitled shits, but we were all young, inexperienced, and somewhat entitled ourselves. The kids aren't really different there. That said, they often lack skills because they come from increasingly broken homes and distant parents who aren't teaching them basic life skills. They're also entering a job market that treats them like garbage, and expenses are absurdly high. Luxuries are cheap, but housing and food are expensive.
They aren't all buying new iPhones and Taylor Swift concert tickets and doordash for every meal, either. Hell, I was still able to pay for community college tuition from a summer job. That's not an option. But we were all told to go into debt to fund a degree because that was the path to success. Now, people have debt but no prospects. Many of their complaints are very valid, and lumping it all together as childish whinging is not cool.
The Baby Boomers already often own homes, have established retirement funds, etc. and the same circumstances which the younger crowd rightly bemoans are part of why the older folks are so out of touch. Their real estate makes them feel comfortably wealthy, and they can't see the disconnect.
