Given they don't have such a high percentage of total wealth and an even lower percentage of real estate, it seems this is largely due to financial education.

Given they don't have such a high percentage of total wealth and an even lower percentage of real estate, it seems this is largely due to financial education. I know a lot of working class people with significant savings (more than I have) but they tend to just put it in a savings account at a bank or perhaps invest in a property to let out. Many people see the stock market as a casino even though you have far less risk in index funds than you do by renting out property.
