But shouldn't the "free market" correct for this? If most people are putting their money into ESG but there isn't a real underlying performance difference, that creates an arbitrage opportunity for people willing to invest in non-ESG?
Sadly, I can already hear the right-wing rebuttal: "the market isn't truly free because of the (bankers) running blackrock! we need govt intervention to ban ESG, then the market will be truly free!"
