I don't agree completely with you because comparing the investments made by the rich people to gambling which has no sure guarantee of profit is a great error that should be corrected because investment is done on a working business or even property with the hopes of making money over time and with gambling is not so due to the fact that gambling is highly uncertain.
No body has become rich because they see gambling for the sake of getting entainment which is a costly deal to do with the fact is that gambling has been a source of making people to lose money and that is one thing that people should be afraid of
That's right, gambling is a company that aims to make a profit and the way they make a profit is from the many people who deposit money and then bet it with a low chance of winning, it is not true that gambling is the same as investment, there is still a strong difference in these two things, for people who have a good understanding of investment they will get profits that may even last in the long term, but gambling is not like that.
