But now, you have people in their 30s closing on the $1M mark... but could very well be in the negative in the mid 20s as they're still in school and/or investing into something, especially if it's a business.
Law school people can be at -100K in some cases before they are done school and then articling.
I make high income... 24... admit my net worth is about only $15K. But my total post-secondary education is about 6 years. Someone putting those 6 years working (especially in trades) would likely be worth a lot more.
