American mortgages are scams. $100k house at 3% interest over 30 years turns that $100k home into $189k giving the loan institution a free $89k all for commoditizing shelter.
I used that number for simplicity's sake since so... so many of you have a hard time putting large numbers into understandable chunks.
I do understand opportunity cost. My gripe is applying it to shelter to begin with. The whole notion of using shelter as a means for financial gain is absurd. That's the reason 2008 happened and why housing is unobtainable now.
