No computer, no internet growing up, but then again, I was born in '74. If I were to guess, probably grew up in the bottom 30% or so. Never had a "new" car growing up, always rented (though my parents did finally 'buy' when I was around 25 or so). Didn't put down on a house of my own until about 2 years ago (43yo at the time).
That said, I've had a tendency to spoil myself since I started making good money over a decade ago (top ~10% or so). I'm not rich, I don't have generational wealth, and I have a modest amount of debt. My daughter just turned 18yo, and is graduating HS in the spring. I'm doing what I can to help her make the best decisions for what she wants to do.
In the end, I kind of lucked out. I got into programming around the right time... managed to recover from a very hard year when the .com bubble burst in early 00's. Despite my parents being together my entire life, I haven't managed to do the same. I'm twice divorced, and currently engaged, and hesitant.
I've effectively had to start from roughly nothing three times in my life. I was kicked out as a young adult. After the .com bust, I had only what could fit in the back of my pickup, repo'd 3 months after 9/11. And after my second divorce, I didn't have much to speak of.
All told, I've been relatively fortunate, and determined through my life to keep pushing forward. I've managed to push through my personality disorder (similar to add/adhd). I've fought with pretty severe depression several times. I push through regular anxiety. Though I tend to push full burn until I burn out (getting close now).
I'm not so much complaining as stating that not everyone doing relatively well started off that well, or had the advantages that many will assume. And even then, you can walk out of a situation with pretty much nothing and still climb back out again. Right now, my heart goes out to everyone who is losing everything they have, watching it all fall apart. A lot of the top 10-50% will wind up in the bottom 50% when it's all said and done.
I will say that of the people from other cultures that I've worked with in my life, those from India tend to have more interesting interactions based on the caste they grew up in. The variance is far broader than most Americans, Russians or Chinese I've worked with. Though most of the Chinese I've worked with are also from a wealthy background typically. Russians who have come up pre vs post communism vary a lot though, mostly from their experience. But those are just my observations.
Okay, going to stop rambling now.
