Rob, do you honestly think anyone gets a "shot" to the upper class? No, you have to take it. You have to steal it! It's not really an 'opportunity' for anyone, or else I would be there.
The best anyone should hope for is middle class. You can achieve it by dropping out of high school, getting a GED, going to a community college, and getting a certificate. Plumber, taxadermy, air conditioning specialist, embalmer for funeral homes, electrician, carpentry, stone masonry... These are all good middle class jobs. You mean to tell me that black people can't land one of these?
If you're born into the upper class, then yes, you've been "shot into the upper class" so to speak.
The fact that you said "it's not really an opportunity for anyone" shows that you understand the concept that economic status is something that's perpetual.
...not sure what locale you live in, but where I'm from, dropping out, getting a GED, going to community college, and getting into a trade isn't the slam dunk you're describing it as. If you live in an area where there's no work, or there's simply not enough of the jobs you describe to go around, then you're still in the same rut.
You can only land the jobs that are open, and as it currently stands, the aspects I mentioned before still play a role. Take a look at the data pertaining to which "types" of names get callbacks for interviews. "Black-sounding" names get less than "White-sounding" names.
You're trying to dismiss all of the factors to keep your narrative in tact. The reality is, you can't. You can't ignore the fact that there are still biases based on race, you can't ignore the perpetual effects of poverty, and you can't ignore the fact that people are still in poverty today due to things that were done to their families and communities decades ago.
If you want to sincerely believe that "eh, they just don't want it bad enough, or they'd be out of poverty", then you're part of the kind of flawed thinking that's perpetuating certain issues.
Of course, when it's poor white communities having these issues (due to the same causes, perpetual poverty, bad education conditions, and lack of jobs in the community), all the same people who chastise blacks for not "dealing with it", are all of the sudden sympathetic to the cause and claim we need to put protectionist policies in place and "bring back coal" in order to get them employed again. Why is nobody lecturing the Trump fan club about how those coal workers just need to snag one of those awesome taxidermy or embalming jobs you described above?
