Yes, in my opinion there is a good side and a bad side, in some countries gambling are prohibited and the user can even be arrested, on the other hand gambling can help the country's economy to develop and attract tourists, for example Las Vegas
Las Vegas is such an awesome city with so many different casinos. The hole city and county lives of the gambling revenues. Unfortunately many other countries don't have such a centralised gambling city. Except maybe Macau there are not really other places to compare. In southern oder Middle America gambling is also important but it doesn't happen so much in casinos. People tend to invest there money more in lotteries. Also scratch cards are very big in these countries.
