Agreed, because in the poor one, it would be do or die. We all know that if we invest as poor people, we will think four times because if we lose this money, we will have nothing to do but cry. Rich people, on the other hand, have extra money to cover their losses, but the lesson is that if you take a risk, you can get the gold; imagine those successful and wealthy people who were at the bottom at first, but risked everything to get to the top, and now you can see them in good shape; it is better to risk than never.
Not all of the rich people got in to that position because they took risk. There are some who inherited their wealth. Then there are a few who got their wealth through unethical means (such as bribes, crimes.etc). But I agree that a large chunk of them are rich, because they took the risk at an early stage of their life. But that doesn't necessarily mean that whomever taking the risk will get rich. Look at the state of ICOs now. The success rate has dipped below 5%. And that doesn't mean that if you invest in 20 projects, you will get one successful project. For some people, it may be 0 out of 20. For some others, it may be 2-3 out of 20. In the end, luck also matters.
Nearly all of them inherited money or power or just took it when they are alive. The ones that inherited because their parents died are the ones we all know, I am not going to talk about them because we all know them. However people like warren buffet, Elon Musk, Jeff Bezos, bill gates and the likes all came from very very wealthy families, they were both paid to survive without going bankrupt by their families, and they were also given networking chances by the families as well, since their family were rich and wealthy that meant even their friends were rich and wealthy and some of them were even better off, so that means with a phone call these people got investors.
Warren Buffet is known as a great investor, and yes he is one that's true there is no denying that, but he started as a senators son who got investors left and right in a period when it was hard to find investors for even big companies. So, let's not act as if anyone was dirt poor and then became a super rich person, those are very rare.
