Unless you imagine for example that Microsoft and Apple are the only computer technology companies to have ever existed, pretending that there are not inevitably losers in a competitive market is absurd. Dozens if not hundreds of others have fallen by the wayside over the decades. I suppose in the scenario where one or two or three companies so thoroughly dominate a market that there's never any thought of new competition, a relatively stable balance between those few
might mean there's never any complete failures: But that obviously cannot describe the situation we are considering, a path of economic development for countries whose industries start from a position with no market dominance and (if your philosophy were to be applied) not even an initial domestic base to build from or fall back on.
Really, I don't think you've made a coherent case for anything at all, as far as I can tell. I'm assuming this is a summary of your views, as it seems to be:
But to concentrate on that only obfuscates your vision of how wonderful the US philosophy of free trade being the way to a better life for all participants, the more the merrier. Why this works so well is because it is the way economics has shown the world works best, if you want to have economic development.
Yet within the United States itself there are fairly well-known counterexamples to that viewpoint in at least two major economic sectors: Agriculture (subsidies and tariffs) and manufacturing (loss of jobs to cheaper labour overseas).
Both of these support the fact that competition inevitably means the prospect of failure, and both of them support the possibility that US trade policy is governed more by business interests than by an idealistic 'best for everyone' philosophy. But both of them demonstrate that the way the world works best, even for the powers that be in the United States, is not through unregulated free trade.
In a world where environmental standards, labour standards, social safety nets, costs of living and state of economic development fall within a similar narrow band all around the globe, maybe. But in the real world, even the biggest economy proves that its citizens and its businesses both still have things to lose if it doesn't apply some nuance and regulation to its trade with other countries.
