Airplanes have value because they save you time when you are traveling.
Every airplane on which I am not currently flying has no value at all to me. In fact, if anything, it is an eyesore / noise-pollution source, so it is a net externality to me (if I'm not actually flying on it). Classic airplanes with aesthetic value excepted.
You have access to fly in an airplane. The average person making a Median wage can afford a plane ticket.
The extent to which I have access to fly in an airplane is exactly equal to the extent that I have capital. I cannot fly on an airplane without the available capital to purchase a ticket. It is not the airplane that makes me rich but my
capital (that is, my savings) which can permit me to purchase a ticket and fly on an airplane. My capital becomes more valuable pro rata with the value of the goods and services which I can purchase with it. So, as the "pile of goods and services" grows, and increases in quality,
at a given price-point, I become wealthier. This is why deflation is a universal pay-raise/dividend payout.
People that are wealthier have more time.
No, everyone has 24 hours in a day. Time is equal.
It's the most valuable thing you own.
This is a category error, time cannot be "owned". Time is just the unfolding of events.
We also live longer because we have access to modern medicines.
Without the capital to purchase those medicines, they do me no good whatsoever.
All of this has to do with investments.
All of this that you're saying is just word-salad.
Without a central bank funding the investments the money is managed differently.
"Managed differently." Differently than what? What are you even talking about??
They hold onto money rather than investing it in things that may not pan out especially when holding onto money is more profitable.
Yeah, that's all the Keynsian theory you've managed to squeeze into your tiny brain-cell budget, and it's total nonsense. The decision to invest has to do with an individual's time-preference which is independent of the value of money, present or future. When the expected value of future money is low, people (and companies) will hold
less liquid capital. As they flee liquidity, they may choose to (a) spend, (b) invest or (c) hoard non-monetary goods (e.g. preppers hoarding ammo). The idea that we "need" any amount of paper-money counterfeiting in the economy in order to "stimulate" the "hoarders" into "investing" because otherwise the economy would "slump" has been debunked to the uttermost. Keynesianism died long, long ago, even modern-day Keynesians have to call themselves "neo-Keynesian" because Keynesianism is so dead.
The central bank punishes savers and this, in turn, centralizes capital. This is what makes central banking Marxism in capitalist-drag. Money-printing causes liquidity to flee into the hands of the bankers themselves, so that the average individual is just one paycheck away from a total liquidity crisis and bankruptcy, no matter what their "net worth" may be on paper. That is the end-goal that central banking exists to bring about. It serves many other useful functions, but this is one of the most important, if not the most important. This is how you put an entire nation on 330 million financial dog-leashes, and you get the dogs to pay you for the privilege of putting themselves on your leash. Central banking is slavery and execrable filth, no string of words in English is foul enough to describe how wicked and sinister it is. It is the most malicious activity I can imagine within the confines of the mundane realm, it is worse than nuclear weapons or bioterrorism. And we've done it to ourselves, supposedly voluntarily. If that is true, then we are a nation of fools...
