> Mainstream investors are often not very good at predicting the winners Index investors don't care about that part.

  A very likely outcome of inflation is for the indexes to underperform and gains to be concentrated in a few big winners (like, say, FAANG stocks). The big winners from inflation are generally chokepoints in the economy, companies that have monopoly pricing power over their industry, so by definition the majority of companies will be losers. Index fund investors are effectively subsidizing individual investors of the winners: the savvy individual investor gets in (looking at the competitive position of the company), their profits rise, the less-savvy individual investor gets in (looking at the new P/E ratios), the indexes rebalance to include more of stocks with higher market caps, and then the index rebalance forces index fund investors to buy in, raising the prices further for shareholders who already bought. To some extent, this is already happening: the S&P 500 is down about 15%, but stocks like Amazon, Zoom, and Beyond Meat are skyrocketing.

    Right, "savvy investors", mostly professionals, compete with each other to be first to set the market prices at their truer values. The index investor just goes along for the ride. > then the index rebalance forces index fund investors to buy in That's not really how it works for cap weighted whole market indices. They remain cap weighted as prices change, there's no need to "buy more" of a winning stock, you already had the stock, it won, now you have more of it (in USD terms).
