China invested their low interest fiscal capacity into developing over decades via coordinated policy of their central bank / industrial strategy nudges to their businesses. China's factory ecosystem and the ability to build stuff meets my definition of a protective moat. Its very hard to replace and one can only contemplate it over relatively long time frames.

US businesses were free to do the same over the past low interest environment, but we did not have the same incentives, not inclinations in terms of prevailing business strategic appetite for factories. In contrast, for big tech, there was interest and appetite for it and significant capability with protective moats were built - but one could argue that software based tech moats may be faster to bypass.
