Okay, so there's this idea that some people have that Jewish people are really good with money and that they like to hoard it, or keep it all to themselves. This idea is called a myth, which just means it's not true. It's like a story that people have made up, but it's not based on real facts or evidence.
The reason why this myth exists is because in the old days, Jewish people were often not allowed to do certain jobs or own land. So, they had to find other ways to make money, like being traders or bankers. Over time, some people started to think that Jewish people were just naturally good at making money, but really it was just because they had to be creative and find ways to support themselves and their families.
It's important to remember that this myth is not true and it is hurtful to Jewish people. Just like how it's not okay to make assumptions about someone based on their race or culture, it's not okay to believe in myths like this one. We should always treat others with kindness and respect, no matter who they are or where they come from.
