The sad thing is that a Cyberpunk dystopia is nominally interesting. Violent, terrible, and impoverished, yes, but also fastpaced and exciting. Our world is dull, programmatic, largely predictable, and extremely boring unless you have disposable income. We all have cellphones, yes, but that doesn't make it cyberpunk.
Having financial plans in place is very important, I know it's hard but making a savings account will help a lot. Even if you just set it up so that $20 a week goes to it it will help.
Most Americans can't afford a $500 emergency so your first goal will be getting to that point in a savings account. Your second goal will be getting to that point plus having funds in your account for you deductibles for your insurances (car, health, renters, etc). Then your out of pocket max for health.
It's a slow roll building a savings account and it's hard to leave it alone but it will help a lot.
Of course even then it's still pretty nerve wracking so one thing that I've done is get a line of credit with my credit union and some credit cards with really high limits that I pay off every month and only use for like gas or groceries. That way they stay open and in the event of a financial emergency that surpasses my savings I'm not completely fucked. Which saved my ass 2 years ago when I had to have emergency dental surgery 3 times in one year. ($10k that I'm still paying off)
Basically trying not to over extend yourself financially will help immensely.
But a massive help is having a healthy social safety net.
I think step one is universal healthcare. For many reasons that we all are familiar with by now. (being tied to a job that has income limitations because you need the healthcare(ish) it provides, becoming bankrupted by healthcare costs, getting kicked out of your housing due to medical costs)
The revolutionary silver bullet to begin increasing housing availability is to eliminate the ability to depreciate assets via the tax code if they are single family detached homes. Many of these rentals are already fully depreciated and will remain rentals. But recently purchased (within 10 yrs.) rentals will likely be sold and importantly they will not be purchased by 'investors'. That shift will provide a flood of homes into the market which will apply downward pressure on prices. More people being able to afford to purchase those homes will free up rental availability, thus applying downward pressure on rental affordability.
Now that only addresses single family homes; there remains multifamily housing to be addressed which will be more complex. A robust government regulatory agency for housing is not something we currently have in the usa, obviously. (see picture) Reforms of those regulatory bodies are needed whereby penalties they assess would have actual teeth. I imagine penalties that remove ownership. I also imagine the countless tax incentives used in constructing and rehabilitating these structures being negotiated quite differently, to include public ownership.
Just a few thoughts here; I haven't all the answers. I'm curious when the last housing project was built in the usa.
