If you could see into the future and know for a fact that you couldn't change a thing about it, would your concerns cease to have meaning?
If the answer is yes, then it is a matter of determining what in your short lifetime, you can realistically change and what you cannot.
For me, I've determined that the things I cannot change are human nature, including my own. What I can do is modify my lifestyle to be exposed to more of the human traits I cherish and fewer of the ones I resent.
That's the conclusion I've come to. Housing prices and inequality simply don't make the list of things I can do anything about and even if I could, I believe I'd be playing human sin whack-a-mole. I whack one sin, another one pops up. At some point, I just had to accept that there are traits human possess that upset me, and find lifestyle solutions to mitigate them, that's all :)
This line of argument scares me, because we are so unaware of how human made our problems are.
"Money is like an iron ring we've put through our noses. We've forgotten that we designed it, and it's now leading us around. I think it's time to figure out where we want to go - in my opinion toward sustainability and community - and then design a money system that gets us there."
This isn't even a question of competition. Prices are increasing purely because the market can bear more expensive housing. The net effect is that real wages after rent are decreasing year after year since the 80s. At this rate, the day will come where the real wages of the average citizen of the US after rent will be lower than in the disaster that was the Soviet Union.
The problem is actually even more complex that simply capital inflow into big cities. Because capital is already centralized around big cities, and has been for a while, which leads to the question, where is that capital coming from? And the answer is that it doesn't actually have to do with capital moving, as that mostly cancels out, but instead with growing inequality.
Also, if your end statement is that it's ok that most people aren't able to own their home anymore, aren't able to own their cars, aren't able to own their furniture, aren't able to own their phones and so on, which is the direction in which things are happening, you shouldn't be surprised when heads start to roll in the next economic crisis. Literally. This is not a small issue, it is a massive issue. The incentive, historically, for the average person to continue participating in capitalism is the promise that eventually they will be able to have their own property, and maybe pass on some capital to their children. If you take away this incentive, the system will likely not survive for much longer. There is a reason why the first people that the population turned against in the Chinese revolution were the landlords. I don't want to see this happen again.
So yes, if fixing this issue will break a few other places, I don't care, we can see what we will do later. This is one of the most important economic issues full stop.
