Many people are scraping by on minimal income and have minimal expenses.
Many others are scraping by because their spending is out of whack with income.
Of course, reining in spending doesn't address the societal stagnant income problem. It only helps an individual not find themselves in a desperate situation because of job loss.
Average age of vehicles on road hits 11.6 years in the United State, which is a new record. When you have low/under-employment people aren't rushing out to buy new vehicles as they were in the past.
This is like saying, "How bad could the favelas be? Brazil's population density is 64ppl/sq mi."
You'll need a citation for the 85% of vehicles are newish SUVs stat.
in SF, maybe
Regarding vehicles. There's almost certainly a bias there. I'm on foot at the moment, and looking at the main road in front of me, the majority of the vehicles are 6-8 years old small to medium care, with a more modern saloon being more common than an SUV.
However many people rely on cars, and unless you're clued in it's easy to overbuy. If my car broke down today and i needdd it to get to work, my options are (broadly) buy an 800 pound banger, buy a 3-5k 5-6 year old vehicle or buy a new vehicle. If I have. O money, then buying an 800 pound banger isn't an option. I don't know where I'd go to get a loan for less than a thousand pounds, other than a payday loan company, or possibly a credit card. Meanwhile, I can walk into my bank ask for 5000 pounds for a car loan and leave with the cash in my account, with no deposit, no security. Funnily enough when you look at the repayments of one of those loans, they come out at near identical to a PCP (or PCH, not sure which) lease agreement on a brand new car, probably a model or two better than the one I could buy with a loan.
I don't underestimate how hard it is to save, but also many people are perfectly happy buying more than they need to maximize what they can do with their income in the short run..
Also: any family should be saving for retirement, childrens education expenses, etc. anyway.. so long as the first-level pool is liquid enough to support emergencies such as this, it should work as well. Might have to work another year when older, do some sort of side job, or take some other cuts, but point stands
On the other hand, its because these things can happen so quickly and easily that one should really prioritise getting a little safety net tucked away. I'm not saying "no-fun-expenses-allowed", but putting away something is a good idea (or paying off (some of) the high-interest debts like credit card debt would be a good too), if you can at all afford it.
On €1500 you can live quite well in most of Europe. And getting a 6-month safety package shouldn't take more than two years to save up.
There's also the fact that as urbanization continues, real estate in big cities will keep raising in price. People will see real estate more and more as an investment. This completely chokes the housing market since everyone overpays, everyone thinks 'fuck you, I want to get mine', housing becomes unaffordable for starters.
Then there's automation which also hits the middle class a lot. A lot of jobs are cheaper fulfilled by manual labor than automation, and difficult jobs are yet out of the reach of machines.
Add to that the fact that ever more wealth keeps getting stuck at the top (especially the 0.1%) and its a very bad cocktail.
A good beginning to fix it would be an inheritance tax of 100% with a cutoff at ${million} (1 million? 10 million? whatever is reasonable but doesn't give your kids a crazy advantage). Assets would count towards this. Right now we're in a sort of pseudo-feudal system where once you're over a certain amount of wealth, your family/kin is set for life. I'm not against working hard and leaving something for your kids, but there should be limits.
A negative income tax (a sort of basic income light) would also help, as there would always be a proper fallback should you ever have bad luck. It also moves a lot of leverage from employers to employees.
Cities (especially big cities) should no longer seek to extract the maximum amount of tax per piece of ground (resulting in only expensive developments) but should have policies that aim for maximum societal gain: this means building housing to the exact class percentages of the population. 10% rich, 40% middle class and 50% working class in the country? That's what cities should aim for.
Universities should be public and admit students purely on merit. No legacy systems, no positive discrimination. However, I am okay with limiting foreign students (say 10-20% max).
Even with all these things I am probably missing a ton of pitfalls. As I said, its an extremely complex, multi-faceted problem.
This. Unfortunately it's fallen out of fashion... everyone wants to become the richest city in the world, even if all it means is that you will price yourself out of it, literally delivering it in the hands of the few 0.1% for whom it's just another new toy to play...
