I would really appreciate if rust analyzer was faster, actually. It feels even worse with the fact that you need to save the file before it updates the type checking (though I assume it's because it's too slow to feel smooth if you do it while typing?).
The reason rust-analyzer doesn't update diagnostics until you save is historical. Originally, people tried to build IDE support by reusing rustc itself, but this proved too slow and cumbersome at the time.
Rust-analyzer reimplemented the frontend in a more IDE-friendly architecture, but focused more on name resolution than on type checking. So it delegated diagnostics to literally just running `cargo check`.
As parts of rustc get rewritten over time (the trait solver, borrow checker) they have also been made more IDE-friendly and reusable, so rust-analyzer is slowly gaining the ability to surface more type checking diagnostics as you edit, without delegating to `cargo check`.
You asked how a price cut translates to raising prices everywhere, and the parent comment answered. Though even without the further raising of prices for the competitors, the effect of many such agreements is that the competitors have a harder time competing, some shut down, and now the Walmart can also charge more because there's less competition.

Well, a lot of dysfunction in government is the result of later evolution, whether evolution of circumstances or of government.
As an example, the combination of senate filibuster (which was around from the earliest days) with the reconciliation workaround (which is pretty recent) results in omnibus bills, which is a well-known driver of partisanship (because you don't talk to the other party at all in order to pass your bill on the floor), and also has significant consequences to individual responsibility (for the same reason, that omnibus bill must pass for your party to do anything, so you can't be faulted for voting for it, and instead you look for carve outs for your interests. If you do decide to hold up the whole bill like the freedom caucus tried, then you get everyone against you and you will eventually fold).
This also has repercussions that for things that can't go through reconciliations, just because the usual way of doing things involves more party dependence (than it would to pass bills another way). This of course also gives more power to those running the party within the chambers of congress.
My point is that things evolve, and people tend to try to explain the current state of things with reference to the 18th century, and while I definitely believe we should evolve systems to be better, we shouldn't ignore evolution that's already occurred.
It's also possible that OP means short term savings kept for circumstances like these, and long term investments bear more cost (e.g. keeping money in a money market fund vs in stocks has different tax implications when you take the money out).
> It's clear from the report I linked that we cannot assume that high school graduates can do elementary school math.
Well, I wouldn't necessarily assume that 100% of anyone with a degree has mastered what the degree is for. So to me the takeaway is that ~90% have mastered the math. And so in terms of the original comment, not necessarily do we need them all to go to undergraduate.
