My parents were mis-sold an endowment mortgage in the late 1980s / early 90s (not sure when they got the mortgage). They later got compensation but it was pitiful compared to how much it impacted their lives and how many extra years they had to work and what the impact was in their eventual retirement.
I learnt that you shouldn't trust anyone to necessarily be acting in your interests if they financially benefit. That was an important life lesson.
So what got me about 2008, is when the Northern Rock mortgage guy I mentioned about told us "well the bank wouldn't lend me that much if I couldn't afford it". Such was his belief that the bank had any interest in his welfare. We tried to say that wasn't the case.
I've talked about the oil stuff over the weekend and the possibility of shortages with friends. And there was the comment that "the government wouldn't let that happen". As if the government have the ability to stop a shortage or end the war in the middle east.
This is naive. It's a form of denialism which is routed in faith rather than previous evidence or likelihood based on current information. It troubles me when people start doing this. I hope it doesn't get that bad, but history tells us, unrest in the middle east can lead to supply shock and shortages and thus we should not dismiss the possibility with such ease.
COVID should have taught people that government can make good and bad decisions. And that sometimes they get it terribly wrong and the UK has demonstrated we have inadequate contingency planning in certain areas. If anything, we should expect it to be in a worse state giving tightening budgets. Contingency planning is often the easiest thing to axe, because it's expensive and might never be needed so is invisible.
I learnt that bad things can and do happen to ordinary normal people when I was younger than most. I'm a realist rather than a pessimist though. The distinction is important.
