The amortization is not a sock-it-to-you scheme. It’s just a fact of how saving and interest accrual works, in your favor when you save and against you when you borrow.
The interest is simply calculated from your principal, so as your principal is reduced, so is your interest payment. If you want to pay less interest, get a smaller loan or a shorter loan period. The lender has to get paid for lending you the money. I am earning 5.5% in my CD because there’s a guy paying 8% on his HELOC.
When housing prices fall back to $250K median, and you get a 30 year loan at 6%, your total interest paid over 30 years is more than you paid for the house. It’s $290,000.
Likewise, when you save money your interest paid to you grows each month, so that by your retirement hopefully, the interest you earn is larger than the money you used to open your account.
