In what ways are people today being convinced to spend money beyond their means?

Trucks (In the USA)

I'm in this FB group that does financial advice with a little sarcasm and jokes mixed in. Suggest that someone should downsize to a car or get rid of their gas guzzling truck they have no real utility for and it's like you've insulted their religion. Never seen such a group of grown adults throwing temper tantrums like that in my life.
