As someone who lives with and associates with younger people (22-27 yrs) I can tell you that this behavior is quite real. People my age (and even more so in the younger ones of 16-20yrs) are completely without any sense of humility or societal awareness. Their creed is selfishness. Who cares about everyone else, as long as I get mine. They do not care about anyone but themselves, not in the least bit.
They’re also completely irrational. “I’m gonna go back to school since I didn’t find a job yet. That debt? I’m sure it will just go away somehow.”
In my generation, I am very much a lonely, near-extinct species. I am fortunate to have found a few friends that are like me.
