I don't know the number of younger employees who end up with 401ks.
I would guess 50/50 as a start. Most good jobs have some sort of 'employer match' incentive. My first job I started my 401k on day 1. Smart employees will take advantage if offered the chance.
I don't think retail or service industry jobs offer 401k options/matching, so there are few incentives in those fields.
I also don't know about the average home situation, but if my parents had 500k in their retirement, and then it drops to 50k, and they want to move in with me, I would be a little upset. lol
