I think the reason is important. If you stick to something because you think it is the right thing to do, that is conviction. If you stick to something because you think you must continue as you have already invested effort into, that is sunk cost. The point that I'm trying to make, that perhaps I have not worded well, is that you must act with conviction, because if you do not do what you think is right, you either not do anything, or do what you think is wrong. Sure, you may be wrong at the time, and you should be open to reflection, and not be prey to sunk cost.
But coming up with convenient excuses to avoid doing what you think is inconvenient but right is not how leaders behave.
And in this context (if that is what you mean), it is definitely not evident that supporting Ukraine is a strategy that won't work.
Unless this is a matter of price collusion (which I doubt as it appears more as a supply demand issue) I don't think this unregulated capitalism is bad. Last I checked making any kind of products involving semiconductors isn't cheap or easy. Maybe it is once you figure out how to, but the R&D costs involved are insane.
We as consumers want prices as low as possible. Suppliers want prices as high as possible. Samsung (and the like) clearly aren't willing to make more of a product at the price that it is currently at (which is a mistake to begin with). There are plentu of other players making ssds, and the prices are all very similar. Something tells me that they're not gonna price things for cheaper because they can't survive that way.
