If 30 year housing loans were not available, housing would be a lot cheaper.
That all said, I'm not trying to be a lending market lobbyist. I personally avoid borrowing whenever possible, and don't even have a credit card. My contention is simply that current lending practices are the cause a lot of societal issues, but if lending did not exist whatsoever things would be substantially worse.
Someone will always have money.
The system we have now may not be perfect but it a far far more egalitarian than the past when there were no loans
