alt Hacker NewsMarkets only "figure things out" in a petri dish economy where:
1) There are no barriers to entry for competitors (e.g. protectionist tariffs, equal access to capital for everyone)
2) There are perfect substitutes available, so transitioning to a competitor is seamless and free (e.g. no requirement to store data in Country X, no vendor lock-in, no security compliance)
3) The industry is not a "natural monopoly" when only a handful of vendors can operate due to capital investment and national/global distribution required (see power utilities, telecoms, petrochemicals)
4) Profitability attracts competitors (won't happen because of #3), but heavy competition prevents abnormal profits from accumulating to a single player (happens because of #1, #2 and #3)
When markets don't figure things out, as is the case around the world, you get a tangled mess of market failures, government intervention and lobbying to neuter proposed interventions.
Markets are never perfect but over the course of history they are a pretty good mechanism to solve these type of problems. Not sure why we think taxing hyperscalers differently is the answer. Government usually does worse than the market when it comes to sorting it out.
My argument is not that market is perfect but that the alternatives are probably far worse, like a new tax on a specific group of companies.
