Our government didn't have the ability to print money? What if going to war meant raising taxes?
We took the control of the money supply out of their hands and instead used free and open source software to create money and move it around?
Our economy wasn't predicated on a target 2-3% inflation rate? What if you were not incentivized to spend your money because it's just losing value every day you don't spend it? How might our consumption/production patterns change? How might that impact sustainability?
The government couldn't move money from the 99% to the 1% every time a bank needed to be bailed out? What if they didn't print away all the value of money you earned? What if when the economy grew, the value of your money increased just as it would naturally if somebody wasn't printing away the difference?
Small but steady inflation is good. The macroeconomic fear is that people will just hold onto their money in the form of raw currency. That's bad. Currency is for a more convenient representation of value. I can't compensate a roofer in computer code, so currency is a stand-in. But it also shouldn't languish or else the economy stagnates. The world used to regularly experience zero inflation or deflation, which hurt the economy. As much as we've had some instability lately, things are nowhere near as bad as they could be.
Of course the flip side - hyperinflation - is also bad, but that's not what we're talking about here.
He is putting that wealth to work by keeping it invested in his company instead of stuffing it under his mattress. That's exactly how it's supposed to work. That wealth is doing work for him and for the rest of the economy in the form of Amazon stock (setting aside various ethical qualms about Amazon). Stock is nothing more than an abstract representation of a slice of a company to allow for distributed ownership and for companies to raise capital. So instead of purchasing goods and services from a company, a shareholder provides raw capital to exchange for a slice of the company. That would make sense for a wealthier person who can only buy so many yachts and massages (goods and services), but it applies equally well to someone who is trying to sock some money away for retirement and have it grow over time.
Good for who? Where does value move when your currency is reduced in value by an expansion in the supply? To regular people? No. Lower and middle class people are the ones who have the most cash, they have a higher ratio of cash to net worth than rich people who can put their money into assets. They have an emergency fund. They are saving up to become property owners.
Humanity survived and grew total economic output for millennia before inflationary paper currency came around. Inflationary paper currency is a relatively recent phenomenon. I'm not saying we should go back to the gold standard, but that ended in 1971. That's pretty recent.
If you live in a hyperinflation environment, you will spend your money on anything because it's better than holding onto that money and see it become worthless. It might seem silly to own 12 blenders, but buying yet another blender is a better investment than simply sitting on your money for a month in Turkey. At least a blender can blend and maybe be re-sold at a later date. That effect still happens in mildly inflationary economies: we are incentivized to buy goods and services we don't need because the alternative is just slowly watching our money lose value. This is not a great incentive to have baked into our financial system when we live on a planet with finite resources.
On the other hand, if your money is expected to retain or gain value, somebody has to really convince you to part with it. Does that mean products are built to last? Built more repairable or sustainable? Perhaps. You will still buy things of course, everybody needs stuff, but at least the incentive is trending in the right direction instead of towards needless consumption.
I can tell you want would happen.
The Collaps of Capitalims. Because Capitalism needs the State to protect it with police force, Military and Bailouts.
Thats the only reason States exist. The Ruleing classes need to work together to keep the rest under controll and to legitamise themselfes with Laws.
States are always a tool of one class to rule over the others. They will never change in that regard.
