Because many families nowadays lack of knowledge in investing, making a good business or creating a good passive income. School system in our society dont teach broad financial literacy they just want us to be a employee of big corporation and work our ass out 9hrs a day. Many people think investing is like a gambling and they also want assurance always when they invest money to a certain things. The purchasing power of fiat money is decreasing when time passed so its better for us to make our money work for us not us working for money.
