Everything new, will invite new abuse. But, that is no reason to not appreciate the benefits and potential.
Do you think that house prices in excess of traditional lending standards (generally 3x a person’s yearly income is considered a repayable amount for a mortgage), engendering debt in excess of a person’s capacity to repay, represents “benefits” and “potential” ? I beg to disagree. Since when did a house become “an investment”. It’s just a place to live, and it’s a depreciating asset. It doesn’t make you any money.
And, to be blunt, I have no problem with people seeking “new returns and taking on risk”, but if they want to do it I don’t think they should keep the gains while others, who were not party to the gains, get to pay the losses, do you ? I’m not in favor of welfare, to either rich or poor.
