This is not really a matter of whether wealthier persons would benefit more, because anyone who has a salary of, let's say, $50,000--if you consider that a rich person--would get a benefit equal to 50% of $50,000. Someone with a salary of $25,000 would get a benefit equal to 50%. So it's what I meant when I said give and take; everybody gets the benefit in proportion to the money they put in. A richer person gets more in absolute terms, but relatively speaking, everybody gets the same benefit in terms of proportional equity.
I just want to make sure that there is no misinterpretation of what we mean. Do richer persons get more? Yes, they do get more, but they put more into the plan too.
