I'm not sure I agree. The answer probably lies somewhere in between. He would like to save money for car and a house. Having it locked into a 401k is good and bad. He's also funding his Vanguard Roth at $6k.He needs to start maxing out what he is putting into his 401K. Don't limit it to 10%. At this point he won't feel the loss and will get used to it. He will be much happier on the back end if he does this.
Not sure there are many 22 year olds that are saving $10k for retirement. Which equates to 20% of his gross.
