> The moral case against gambling transcends American Protestantism. Many Asian countries ban casinos and others restrict them to foreigners. In South Korea, 13 of its 14 casinos are off-limits to Korean citizens. China has no casinos at all, except in the enclave of Macau.

Maybe I'm missing something, but this doesn't look like a moral case at all, rather a practical understanding that mass gambling is a profitable social ill, so better to take money from foreigners while keeping your own citizens away.

If these countries had a moral "gambling is wrong" belief, I don't think they'd allow foreigners to participate either. And if they really believed in this cause and had the ability they'd try to lobby/coerce others to their cause.
