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 will have the problem 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.
I totally agree with both you, here my country Nigeria, i dont have to go far to see how a city or nation of sports gamblers would look like, i just go to the ghetto, the rural part of a city, there, it is filled with youths of all ages, even old men who are so lazy to work but would rather sit at the betting shop all day chatting and ranting about stuffs that make absolutely no sense while smoking and drinking.
Indeed, a nation of sport gamblers, to me , would be one of the most useless nation in the world as such a nation will be filled with irresponsible men and woman and even children, everything in such a nation would be at their waste state both basic amenities, health care etc. as none would pay any attention to making sure this things are put in place and working as it should, all they will always think of is gambling, gambling and gambling.
May such a city or nation never come into existence in this world.
