Nobody said he saved it all in two years. What if the parents paid for college and he worked and saved the entire time?

I’m in a similar situation but with less saved and less income. I probably make half as much as him but since I was fortunate enough for my parents to pay for my school I was able to save everything I made during high school and college, leaving me with about 80k after 3 years out of school. With even more income I can see how he can achieve 100k with no problem.

Though on the other hand, part of the reason I do have a lot saved is because I don’t place any importance on the car I drive so that’s why I go for cheaper/reliable/efficient over fast/expensive/namebrand.
