This is another place where modern capitalism struggles in an area that requires large capital investment producing payoff after years of startup costs, and the buy side is volatile. We've seen this recently with rare earths, copper, and some other minerals. DRAM is almost in the same category.

China has an advantage here, once domestic DRAM production finally gets going. DRAM policy can be set strategically. China's economic planners may choose to provide DRAM to domestic manufacturers rather than export parts, even if exporting parts would be more profitable in the near term. That's already being done in raw materials. Conversely, if external suppliers have lower prices, there may be a policy decision to buy domestically to keep the domestic manufacturers going. Done with the goal of leveling production, this can work. Done stupidly, it becomes a money drain, of course.

Probably China controls the DRAM market around 2030 or so.
