It's because that's how we've all been conditioned to think/plan financially. I truly believe it's what the powers that be want from the plebs. They want us to be hamsters in a wheel of debt, spending as fast as we can and living hand to mouth. No one (well, very few people), actually save up to buy anything expensive these days, it's all on tick.
So much stuff on monthly subscriptions/repayments, it's shocking when you take a step back and see what's really going on. All these people with nearly new cars that they can only afford because it's on a monthly payment plan. All they're doing is servicing the depreciation on an asset they don't even own.
Same with sending every one off to university at 18, charging them eyewatering fees, and then generously lending them a truck load of money. It just encourages young people into a lifetime of debt, conditioned them to it, so it becomes the norm. I actually think that these days, university is less about learning an academic qualification, more about teaching youngsters how to spend money they don't have.
But when they've been conditioned into spending beyond their means, which credit and subscription based spending encourages, the concept of scrimping and saving and going without the latest mobile phone, a nearly new car, and foreign holidays, is totally alien. Shit, even what some people spend on takeaway coffee adds up to an eyewatering amount when you look at it on an annual basis.
Then you've got all these youngsters bleating about how they can't afford to buy a house. Well, that's something that's never been easy, even when property prices were much lower compared to earnings (interest rates were generally higher, so the monthly payments were higher). So often the 'average house price' to average salary ratios are quoted by the media. But that just leaves youngsters disenchanted and thinking they'll never be able to afford to buy a home. So they just give up and don't even try to save a deposit.
Reality is that very few people jump on the housing ladder half way up it, with an 'average price' home. You start off small, with a flat or apartment, and then work your way up as you build equity (and hopefully rising prices and salaries help along the way too).
So it doesn't surprise me at all, and I think it's exactly what the higher ups want - they need people to keep spending to keep the bloody economy from collapsing.
