“no learning, no davening really, no bentching, not caring about nivul peh, onas devorim, lashon hara.”
Sadly, one can find people behaving this way across all socio-economic groups. Every person must grapple with his/her yetzer hara and make the right choices. No one escapes challenges.
On a more positive note, if you look for them you can find many people who do the right thing. Seek them out and try to learn from them.
That’s much more helpful in the long run than overgeneralizing about an entire class of people.
