There is no way US equities can outperform international over the next decade
It's basic fundamental analysis that says international equity, pretty much every other country actually, has better price ratios relative to current earnings / cash flow / sales etc... So, investors currently believe that the US has the ability to outperform all other countries over the next decade.
That is a horrible assumption. For starters most all of the other countries already fought with their demons a couple years ago, EU with an actively invading Russia, China with a property bubble collapse that's basically done now etc... The US never hit any pain from COVID cause it debt funded its way through. Now our gov't interest rates are worse than Greece. That macro factor alone, coupled with all the tariff crap, a dwindling AI profitability prospect (why are they cancelling all their data center leases), an imploding EV scene...
Who on earth would think the US has 'better' odds than somewhere like South Africa?
