And
... what does this have to do with things being worth what people are willing to pay for them?
Regardless: yes, being successful has a lot to do with culture. As in, it's a damn shame when people who aren't equipped (or dedicated to) raising successful kids go ahead and have kids anyway. Look at Baltimore. Kids going to school and learning how to be humans and winding up as fairly comfortable middle class people, just miles from kids who get exactly as much (and often more) spent on them at school, who have subsidies available for college and countless other programs, but whose neighborhoods tend to be full of poverty and squalor.
For you, it's all about race. Because you're lazy, and/or you don't want to stick your neck out and talk honestly about family and neighborhood culture. Culture is not race.
And while you're deliberately mis-reporting and muddling things: Costco's basic membership is only $55. And there is no credit check necessary - feel free to pay cash. And an entire family, and every friend or neighbor they want to bring with them, can walk in and load up on things at sensible prices and check out on one person's card. Your fake barriers to spending less on things like commodity food are BS, and you know it.
Sure would be convenient if there was a Costco in easy walk-up range in those rough neighborhoods in West Baltimore, right? Ask the liberal democrats who've been running that city for decades why that specific area is so hostile to investment, why the people who live there are scared to carry bags of groceries down the sidewalk, and why it's so hard to find people willing and able to work in stores.
Being born poor and white is STILL a better result than being born black and richish
Really? Shall we start comparing the life prospects of poor white kids in Appalchia to the kids born to dual income white collar households places mostly black areas like PG County, outside of DC? Yeah, don't trouble yourself. BSing about it won't change it, as much as you'd strangely LIKE the narrative you're going on about to be true. Why, I don't know.
