2. Bigger paychecks.
Not all rich people are gamblers but they certainly have more chances to gamble if they wanted to. According to data, the higher the income is in some countries the more people gamble in that country. Since the average citizen is earning a lot, even if they spend quite a significant amount of money in gambling this will still not cause financial doom.
This is not entirely true, if we are referencing the statistics of people who actually gamble and we are measuring this in respect of the rich and poor, then I'll be quick to point out to you that a higher number of the poor people gamble because they see it as a means of survival. Most of them do it in physical casinos as against the online casinos that this reference may have been drawn upon.
Most rich guys are very busy and gamble less, only that they gamble with higher amounts when they do and that would compensate for a lot of the plow people's gambling amounts combined together.
