Stefan has on multiple occasions mentioned that before the 07 financial crash laws were set in place that forced banks to lend money to people who couldn't afford it. My google skills are up to par. I can't find anything on this. Does anyone have some names of politicians, laws etc? I tried looking in the different sources linked to on the shows but I can't seem to find this out. I'd appriciate a hand. Thanks in advance!
