My mother, who was born in 1935, will not even buy a entry for a church fundraising raffle because that is "gambling" and she was raised by good Presbyterian teetotalers who absolutely did not approve of gambling in any form whatsoever.
A bit of that attitude leached off on me as well, but I have noticed that it is almost completely vanished from American culture.
Gambling used to be something that whole swaths of society looked upon with absolute contempt as nothing but an unmitigated vice.
