I think all the religions taught here in the United States except Native American and the Mormon religion are from the east. I know many Buddhist retreats and lay centers that have tried to establish alms rounds, it's been difficult. I think it is because the state took over welfare and know JP Morgan hands out the food, I mean money...

Back in the day, even during my time as a child the needy were taken care of by the community they lived in, times have changed and Buddhism doesn't fit into a state run model unless it is the state religion. Korea, China, Japan had Buddhism for it's state religion, much like the West had Christianity as its state religion and the Middle East has Islam for it's state religion. Thank you @mountainjewel.
