Right but the word "capex" isn't a magical amulet that makes balance of payments and cash flow problems disappear. Plenty of companies have been wrecked by overextending on capital spending.
Yeah, for sure, but it's also usually something that's a bit easier to trim when needed, unless they got way ahead of themselves and went deep into debt to do it. Most public companies have much worse debt:equity ratios.
They can stop building out their capacity there, if they want.
