that's why it's probably better to measure money in terms of percentage of total wealth instead of total amount
I see that a lot of what we call rich or poor has to do with people being able to manage their finances and have emotional control too.
calculating risks and knowing how to manage it is a must
So this would mean that the poor should invest less but i think even if the person is rich, he or she should also invest less in a single bet or game. Since gambling is risky, why would even a rich person take a risk of putting high amount of money (even though he or she can afford to lose that money) ?
The more you gamble with care and taking less risk, the higher are the chances that you can longer remain in gambling and keep enjoying while making small incomes. The moment you try to become greedy, take big risks you will start to lose your money and your portfolio.
For me, no matter you are a poor gambler or a rich gambling, in both cases, there should be no need to invest more.
