Also, why are governments not creating sensible upper limits on lending and interest rates? For instance, if I can afford to purchase the raw materials and build a house myself in 10 years with my own two hands, assuming I'm not working a job, then why is a bank allowed to extend interest over 5 times that timespan and make me pay e.g. 1000% of the raw materials price in profit to them? They are preying on peoples' basic need to have a roof over their head.
