Have fun when the AI bubble pops and SP500 has a negative 20% return and you are `borrowing like crazy' at 6% interest if you dont get margin called.

And if it doesn't pop? I mean I don't even disagree with there being massive bubble risks, but like my comment was more aimed at the fact that high margin debt doesn't mean anything without knowing the return of the asset you buy with debt and the debt cost.

Let's not even get into the fact that in jurisdictions with wealth taxes and interest deductions from income levering up actually "cuts" your tax bill.
