the greatest is an addiction. when it has been defeated and wants victory to be back, then the gambler will keep returning to the table and bet again. it will continue. and the impact is, they will become lazy to work.
There are very few people seen in this world who behave like crazy people because I think its better for the person to avoid the thing which is being avoided by majority of the people. definitely, it contains some sort of danger in it thats why the people before you were not trying and a normal person would also not try because sometimes accepting other people advises is a good thing.
What is funny is that people understand the consequences but they still try it anyway. It is not like they are crazy but they are just simply not ready to face reality that no matter what, luck cannot always play out to their advantage all the time and that affects their judgment and mentality a lot that they simply forget themselves and get engrossed in their gambling activity until they face the huge consequence.
At least if anyone wants to gamble, they should do it with sense. One fact is that it is not everyone who gambles that will always end up getting screwed as you have said, some simply do it for the fun, but those who tend to look for something they can never find in gambling such as making profit or making a lot of money like it is an investment are always the ones who end up facing the crazy fix that gambling puts them at the end of the day as they tend to find it very hard to control themselves.
This is how stupid human beings are or we can say how lazy and sloppy people turn out to be. All they want is to have money for survival without putting any efforts. Like there is going on some charity show in casinos that they will make all the players rich financially settles people. Anyone who is greedy or fails to control his love for money but do not want to work will end up gambling and most probably, he will be losing what he had before.
