In many ways the US is a very prudish and conservative country. This is indicated by attitudes toward gambling. The way I see it, there are many groups who oppose gambling (usually religious based), as seen in the varying laws in different states. Some such as Indiana prohibit all slot machines, while some, like California, limit legal use to machines 25 years or older. Then there are the more “progressive†states like Ohio and especially Nevada, where all slot machines are legal, regardless of age.
We are a curious country of conflicting views and attitudes!
