Cause Americans are obsessed with Rugged Individualism.
If you are in trouble, you don't accept help, much less ask for it. You pull yourself up by your bootstraps and turn your fortunes around with grit and determination using nothing more than the loose change in your pocket.
Thats how anyone that needs help became nothing more than social parasites leeching off the rugged individualistic success of their betters.
Thats why Americans, on the whole, have all but erased empathy and good will towards others.
Its why 1/3rd of the country actively votes for weak, pathetic fascists who poorly playact as strong man. Its why 1/3rd of the country didnt bother voting, because they have no problem with fasciatic strongmen punishing the weak and the other.
The New Religion of the American Orthodoxy is basically "Fuck you, Got Mine".
