The problem is the AI bubble, without it it is speculated that the US economy might actually be in a recession [2] - effectively, that web of investments, deals, ownerships, purchase contracts and god knows what is nothing more than wash trading that will come crashing down hard.
That is why for the 99%, the economy doesn't "feel" like 4.3% of growth. If you're not in AI directly or at least adjacent (e.g. datacenter or utility construction), you don't feel any of that money.
