The economy is doing pretty good. Lots of people making a ton of money, savings growing to record levels, early retirement looking very easy to pull off, etc. I've been very happy with US markets. Not sure which metrics you use, and it's crazy how much you blame the President for inflation when he is literally has zero control or influence. It's a product of a market environment and there was no way to avoid it from all the pandemic boosting. Plus, it's the Federal Reserve which sets rates to combat inflation and such. Also inflation isn't all that country-specific. We've had it too up here. Especially in core services, but it was everywhere.
The only metric I care about is the direct comparison between what I am currently earning/currently worth, and how much things cost me. My best guess is that during this "good" economy I've lost close to a hard 20-25% of my net worth. That's a complete unmitigated disaster by any measure, at least from my perspective. I barely know anyone who is better off as a result.

Emily's answer: pi * r ^2 * h -> I even checked it on the abacus.
You can easily remember these kinds of formulas by remember the way they are constructed. Start from the flat plane equation and multiply it by the height. So for example, let's say we want the surface area of a cylinder with no tops or bottoms: that would just be the length of the circumference of the circle 2 * pi * r multiplied by h its height. If you want to add the caps you need their surface area. So you'd add 2 * pi * r^2 (because there are two of them) to 2 * pi * r * h.
Now let's look at a special case: a cylinder with radius r and height r. If we wanted the surface area of that specific item we get 2 * pi * r^2 + 2 * pi * r * r (which was h=r) = 4 * pi * r^2 -> this is a really interesting result, because it's the derivative wrt to r of the volume of a sphere with the same radius: 4/3 * pi * r^3... I wonder if there's a relationship there... more on this in a later post.
IDIOT!
