Why won't someone call out Dave Ramsey's insane mortgage advice?

he demands no more than 25% of take home pay on a 15 year old loan. How the fck is this possible? the median income is 80k a year. That's 4500 a month after taxes. You need a 1100 payment. You would have to have a 100K loan so you're talking about putting 300k down on median house. That's complete and utter insanity


why won't someone tell him this?
