A huge number of people on our planet live from paycheck to paycheck, so they do not have money not only to buy blue chips, but also do not have money for their own homes or personal cars. Such people are forced into the trap of today's banking system and become a kind of slave.
Social gap is still a big matter in every country, the poor have no choice than working for the rich and get paid with minimum or low salary.
On the other hand, I'm not sure if we could include gamblers on this category, since they seem to have a lot of spare time and money to maintain their hobby active frequently. So, I don't think they have any excuses to develop the wrong mindset when planning and tracing strategies on what to do with the earned money. Lottery and jackpot winners should be examples of success for every gamblers, rather what we see for real are people wasting won prizes until going totally bankrupt.
I believe in part it's due to an uncontrollable excitment these people feel for having an amount of money on their hands they have never dreamed they could achieve before. So they somehow lose contact with reality and waste everything irrationally.
