I don't like a nation of sport gamblers as they would be in default debt really soon because no one would really work,all of them would have their mind in their betting.
A nation of sport gamblers is at the danger of having citizen who are mostly Irresponsible. The gambling will not affect everyone making everyone irresponsible, but it will surely have the number of irresponsible people more than the responsible. The irresponsibility is people who gamble without control, and those that will do anything just to keep getting money to gamble including involving in crime.
