This is pretty close to current concentration, but the current top 10% is basically all technology except for Eli Lily at 1.5%, so in that sense it's arguably unprecedented.
There's a good chart here on page 5 of top 10 weights over time, and on 6 of how the 1965 top 10 fared to 2025.

To me the diversification hedge options (say GUNR) seem like they are helping you get closer to regime neutral. Or in other words you are giving up returns to cover more macro scenarios and betting less on what the future looks like.

It also increases the immiseration of those in the areas replaced[3], which is likely a contributor to rising populism and political instability. Most of this malaise is just hidden in places like the Rust Belt.

Competing in terms of production is realistically not an option (Triffin Dilemma, strong currency means exports other than tech/finance are inherently noncompetitive). Competitive exports would require giving up the dollar as a unilateral reserve currency, and China for the reverse reasons, at least for now, does not seem to want the Yuan to be a reserve currency. My personal read is both sides wish for something like the current system to persist but on more favorable terms.
I agree China has been actively taking steps for this scenario, but that they're continuing to make strides seems to indicate it is still an issue. I think we're still in the thick of it before a victor is conclusively decided either way.
China possibly expecting something to this effect has recently built up both it's coal and renewables capacity, as well as an extremely large SPR.
Colonial economies did not require the lowest earners to contribute to demand nor Rome when it transitioned from small farmholders to consolidated farms and slaves, or modern gulf states. The examples are arguably unhealthy as economies long term, but practically they may persist for fairly long periods of time.

If you're (understandably) concerned about the security implications most of the changes can be done manually going off the docs.
