I read the subject as Mustaschism... Schism.. Freudian slip? :-)
Many, if not most, Americans are carrying serious levels of debt. So a TV show or movie showing serious debt is depicting reality.
We tend to forget that Mustachians, FIRErs, Frugalistas, etc. are statistical outliers and anomalies.
Since season 1 of TBBT, I claimed that Penny was getting money from her BFs and drawing in huge tips at her workplace.

I can't watch Friends. Have never sat through an entire episode, something gnaws at the recesses in my noggin. How do these guys with low-end jobs in Manhattan (except Chandler and Ross) manage to live really well and how come the mid-1990s in NYC was all white? Very rarely did I see patrons of color in the coffee shop, but we all know NYC is extremely diverse.
And the drama was all first-world problems.
