all I know is he started from scratch(no money passed from family). He started investing after college, after losing money to stocks for 1 or 2 years, he got into low cost index funds. Right now he is 37 and got about 1.5 mil in his account (mostly 401k and individual after tax). He started entry level position in a fortune 500 company (chemical) after college and have not changed job.
Not true. I have a friend who has 1.4mil in his investment accounts(mostly Roth IRA and 401k) by age 35. He started around 25. He does mostly low cost index funds from Fidelity and Vanguard.
