It's just how the math of such long-term loans works out. For a fixed rate of compound-interest over a loan, the most interest will be paid up-front. The longer you extend the lifetime of the loan, the bigger proportion the total interest that will be paid, and it is always front-loaded, meaning, the principal goes down the slowest at first, and faster later-on. For example, for a $400,000 home loan @ 6.1% over 30 years with 20% down, you're going to pay $394,258.58 in interest (try
this mortgage calculator). So, on most typical 30-year home loans, you're going to pay about twice the price of the house, all-told and about 50% of that will be in interest payments. As you extend the term of the loan beyond 30 years, the proportion of interest goes beyond 50% to more than half the total cost of the purchase. Which is utterly ridiculous and even the sheeple, for all their renowned stupidity, can see through that laughable charade. You want me to pay MORE than the value of the house, just in interest??
FDR is guilty of many things, but this particular detail is not specifically his fault. He just facilitated the scam, he didn't implement this specific detail of it...
