I think the really interesting part is when Brett and Lauren start to realize their lives are closer to S and C than Trump/Bloomberg as well:
Are living paycheck to paycheck - it's a bigger paycheck and there may be some savings, but they also have bigger bills, the mortgage, student loans etc.
If in a marriage, both parents are working
Are having their children educated by a decaying and underfunded public system - or paying too much of that above paycheck to get them into a private school/ or higher mortgage for the better public
Have little to no savings - they have some, but again, bigger bills
Have little to no equity in their home - they might, if they were ever able to get a down payment together to buy that house
Cannot afford to educate their children past high-school without crippling debt
Would be wiped out by a job or health emergency - better able to handle the unexpected simple knee surgery, but one major care wreck could really tilt their world upside down
The family breaking out of this caste often requires some generation to literally or metaphorically hit the lottery - better odds than the former, but the ability to afford their children's college and their children's access to traditional gate keeping institutions (the Ivys, certain prep schools, unpaid internships, connections, even acting/music etc.) is getting smaller
