Should people be more financially responsible? Yes
Are they today? No
In a rational world payday loans, predatory auto loans, BNPL, perpetually rolling credit card debt etc would not need to exist. Yet these sectors are rapidly growing and companies in it are thriving.
I'm saying the specific claim of "most people live on credit cards as bridge finance between paychecks. when I mean most people - I mean 50% of the population" is false.
