You make all these assumptions about them, judge them... based all off things you failed to teach them about value. And now you're sitting here gloating about how the economic situation around them is different to how it was when you were young, and didn't need a smartphone for work. You even disclaim that they got the phones as part of a phone plan EXACTLY THE SAME AS YOU DO, but you have to inflate the cost of the plan dramatically to make your smug bullshit make sense.
Holy fuck. How stupid are you? Just about everyone's parents are doing better financially by the time they have kids vs. how they were doing when they left home. Why do younger folks think they should be doing just as well as their parents are doing as soon as they are out of school?
I grew up poor and left home in my mid teens. I worked 50 hours a week third shift my last two years in high school and worked full time to get my degree and did my first 2 years at community college to save money. There were times I lived off of peanuts and instant ramen. I see people bitching about being broke but somehow manage to stop by StarBucks once or twice per day.
No one needs the latest greatest shiny new phone. You can buy a used phone for a lot less. I usually get whatever the best used phone I can get for $200 these days. I see so many people getting a new $1000 phone every two years and have to wonder why. Just because someone who is in the later part of their career can afford that doesn't mean anyone should, nor should you think it's unfair that you can't do that at 25 years old.
You accuse them of doing the things you do badly because they have less resources than you do, as if this is proof of some generational thing... because it's obviously never occurred to you whose fault this is, because you're never to blame for anything that isn't brought to your attention you special fucking snowflake. Why didn't you teach them better habits? What kind of parent are you? A terrible one. It's amazing that they'd ask you for advice at all, based on what you've said. They either don't exist and you made them up for rhetorical purposes or they don't have friends because you failed to give them the opportunity to socialize.
It seems to be a generational thing. The amount of shit younger folks seem to think are necessities these days compared to when I was young is insane. When I was in high school I owned 2 pairs of jeans, a couple shirts, my couch was from goodwill along with my cookware. I didn't own a TV, or have a phone(land line) because I couldn't afford such things. I had a used acoustic guitar I got for $20 and an electric guitar because I played in bands for extra money.
After school I worked may ass off and eventually made decent money. It's kind of hard to listen your victimhood mentality.
