I remember the 2008 crisis and it was even worse than that, banks got their money back and then they got to keep the houses as well, but obviously banks do not care about them since they want to lend more money for them or to sell them to someone that can actually pay them, but then when the same people that lost their houses because their mortgage was now more expensive than the actual money their house was worth tried to buy their house now that the prices were cheaper banks simply refused out of spite, banks never really lose it is heads they win tails you lose when it comes to them.
The thing is, if you are a ruthless banker, you should not be a banker, that is the point, nobody that would be a great banker ends up being a high level banker they end up being crushed under the requirements to go higher, they try to be good and they end up losing it all. This is why the only bankers at the top are the ones who have achieved those ruthless requirements and that is why they end up being at the top while doing all sorts of near criminal stuff.
Not giving people their house back even if they want to pay for it? That is the type of thing that bankers do because they are idiots, they should know better than it would be a great business decision to do that but they end up not doing it. And we are talking about people who paid their houses in full but remortgaged their 30 year houses and lost that, sure bad financial decision but still it is better to give it to them to someone else.
