Total US mortgage debt and corporate debt are around the same size - roughly $15 trillion each. Mortgage and corporate bondholders have both seen principal losses in recent history. Fed support is pushing down both types of rates, and it’s not obvious to me that one is somehow unfairly pushed down more than the other.
Perhaps you are one of the few who can get an uncollateralized loan for billions to pursue endeavors that cannot pay for themselves and be able to continue to finance it with more uncollateralized debt…
Equity for funding is not the same as a loan or debt on the capital structure, though it does have some overlap because if equity stake has no preferences in the event of compelete loss, it will be as worthless as uncollateralized debt, but, VC funding is far from the notional value of the uncollaterized debt that is allocated to relatively few endeavors out there today…
Perhaps if VC's funded many more things to the same notional as the uncollaterized debt extended globally (not "valuations", not re extending to the same companies after previous funding from the same one), I would agree to degree , if they faced 100% loss of value extended if the endeavors they funded didn't pan out (not considering firesales of assets that may have been used in such endeavors during the bankruptcy/liquidation process).
