How is it possibly true that ZERO companies will be created if interest rates go up.

How many businesses are equity funded in the first place?

We did not have capital to start our business.

Most small businesses starting from zero can't get capital in the first place (excluding personal funds, family funds which aren't usually charging interest tied to the Fed benchmark)

Those tech companies that do get tons of capital despite negative value are somewhat unique and for sure interest rates will eventually affect that. Valuations are already starting to come back to at least the Stratosphere ;)
