While I tend to agree with what he said about making money generally, i am still trying to find any reason to believe that the emphasis he used is true, that is, I do not believe his opinion about gambling house verses investment banks to be true.
I couldn't have agreed more with what he said. Aside from this dude being a musician, he does make some sense most of the time, but in a more complex way that won't be easy to read.
If you look very well, the local gambling houses are always located in areas where individuals are trying to make a living while struggling with their daily life activities. There are no good offices or much development around that area. Such a place is the perfect target for a gambling house because you will get all the jobless people that you need to fill out the game house every now and then because they don't have much to do.
Adding to that, we can also agree that most of the time, those who can barely make two square meals a day and are too lazy to work always look for the easiest way for them to escape poverty, and most of them see gambling as the perfect solution for them to achieve that, not knowing that they will still end up losing all that they have.
