I'm not a frequent user myself so I'm probably not the best to answer on the usability front, but for the combination of high TPS and low price volatility I'd probably recommend using one of Ethereum's stabletokens (DAI, USDT, etc.) on one of its layer-2 networks (such as Arbitrum or Optimism). Stabletokens are cryptocurrencies whose value has been tied to some external measure, in most cases the US Dollar, so they're ideal for use in commerce.
Yes, again, I'm talking about large-scale trends, not the current spot prices. I don't live in the United States anyway, most people don't. Note how cheap it is everywhere else?
Maybe something got stuck in the nozzle, partly clogging it. Try cleaning it. A trick I often use is to start the nozzle preheating and then yank the filament out of it as soon as it becomes warm enough for that to be possible, that usually pulls whatever crud was stuck in the nozzle out along with it.
That's not true. Originally insulin had to be isolated from animal pancreases, a costly procedure. The first handful of humans to be treated with it were literally the children of wealthy politicians, a congressman and the secretary of state. They were the only ones who could get access to it. It's now produced in industrial quantities using recombinant bacteria to synthesize it. It's routine.
I'm speaking about large-scale trends here. Obviously the prices of things have their localized ups and downs when you look at them on the scale of a few years. But I'm not expecting to need elder care for quite a few decades yet.
This really just shines a light on a more significant underlying problem with scientific publication in general, that being that there's just way too much of it. "Publish or perish" is resulting in enormous pressure to churn out papers whether they're good or not.
The last half-century of economic trends supports my expectations, actually. Treatments have been getting cheaper as technology advances. New treatments tend to be expensive, yes. But then as they become older they too get cheaper.
Small towns in the rust belt are not the entirety of the United States. Different people value different parts of it in different ways, just because the part of it that you like isn't doing well doesn't mean it has no value to anyone else.
Then the credit card companies crank their interest rates higher and restrict the credit they extend to your kids to compensate. It's not "free money."
Everybody wants everything at no cost. That's not how the world works, though. If you earn $X a month and want to save some of it as a long-term investment, you simply cannot spend $X a month. You can't have both.
There are indeed some people who have no choice but to spend $X a month, their basic expenses just can't go any lower without literally ending up on the street or straight up dying. Those people do have a real problem and I sympathize with them.
People who say "I want to save money but I also want to live in the nicest possible house in the nicest possible neighborhood" I have less sympathy with, because they have a choice. I face that choice myself and instead of griping about how I can't have everything I want with no sacrifice I just go ahead and make the choice. I don't spend all my money each month, and as a result I don't take vacations as nice as I could take and I don't have as nice a car as I could have. But in exchange for that I've got plenty of savings built up.
