If it is bad to generalize, there are rich Jews and poor Jews, just as in any other culture, it is a fact that Jews on average are successful from the economic point of view. and this has nothing to do with their genes or destiny, the only thing they have is a culture that fosters financial success.
below 5 things that Jews do that the rest almost never do
1 Move
If they have a good business idea, they immediately take action and move, they do not wait for the "best moment" to arrive.
On this page there is a 5 step guide to follow to get your idea going.
Why Jews have so much money
2 Invest
almost all Invest but also investigate before investing, for example if you think that Blockchan is the technology of the future, it is worth investigating and investing in things related to that technology (they do not necessarily have to be cryptocurrencies) on this page there is information about investing in blockchain.
That's just an example, if you think it's a good opportunity to invest in the Japanese stock market, or in gold, or in nuclear energy, do it, but first do your own research.
3 team work
They help each other, if someone sets up a restaurant, the people in their community will go to that restaurant just to help him.
Thanks to social networks, groups etc. Nowadays it is very easy to belong to a community of mutual help.
4 They have many businesses
It is not that they are financial geniuses, they simply have many businesses (or are partners) they fail 90% of the time just like everyone else, but thanks to their diversity there are one or two businesses that thrive.
There are many platforms where you can invest in business and become a partner, more information here
The formula is very simple, if your business does not work, maybe if your partners work.
5 start young
Many times since they are teenagers they are undertaking something, while in other cultures they tell us to "look for a part-time job" if you have adolescent children help them by starting a business, it does not matter if they fail, anyway they will learn a lot.
