One of the best tools for the modern, non-finance, average every day person is a 401K/IRA.
If you consistently contribute to it for years you will become rich.
It’s one of the best indicators in the US for whether a person will have a secure retirement or a tough retirement.
You don’t need to understand stocks, you don’t need to research each company and stock pick, you don’t have to know anything except for the fact that if you consistently contribute to it, chances are those investments will grow and you’ll have way more money in the future.
You don’t have to know anything about finance and money to become rich, just invest in a retirement account and it’s statistically proven to lead to a better future for almost everyone.
