I guess I'm confused. How are we separated by socio economic class?
I see people moving up and down the economic ladder all the time, unless they decide to stay where they are.
I had a co-worker that decided to tile his kitchen, and then invite his neighbors over to show off his work. He told them if anyone was interested to let him know, and he would give them a quote. Soon he was making more money on the weekend, than at his full time job.
No came by and said "Sorry you can't do that, because you are in the wrong socio economic class.".
And I had another co-worker years ago, who was taking one college class a semester, because he was paying his own way through, and couldn't afford more. He's now an executive at a fortune 500 company that every person here would know if I said the name.
No showed up, telling him he was in the wrong economic class to do that.
The people who segregate themselves, do so by choice. If you stay working as a burger flipper, that's a choice.
