your speech is very enthusiastic, but is evident that you know few Chinese companies, It is a reality that competition is fierce and margins are horribly low.
Then such a business model will not be viable. Given the 100%+ tariffs we are witnessing, it is unlikely any export-based businesses not pursuing a blue ocean strategy will survive.
Then capital will be allocated towards other fields, as the market demands. It is unfortunate it had to end this way but both sides will hurt from this duel.
Just an aside, but margins being low implies a very efficient market. In practice, large profits are not due to innovation, but due to monopolization and rent-seeking. This is also connected to the falling rate of profits issue, which states that as capitalism progresses, the rate of profit for any industry gradually decreases. What you see is the natural result of free-market competition without rent seeking jacking up profits.
