If a business is solid, no funding is needed. Or, if it is needed, it's easy to get.

Forming or becoming a capitalist organization using Other People's Money is a perfectly valid approach for an entrepreneur to take, and if so whether funds should be raised from VC's or other sources is the kind of uncertian decision that entrepreneurs have to rise to, yes.

But it's also possible to be a complete entrepreneur by using only your own resources whether that is primarily funds or not. You may or may not need to choose a low-resource-requirement business to operate. You may also survive or prosper in a capitalist environment and/or compete in a capitalist market without being a capitalist at all.

At least since recorded history anyway.

IMHO the top of the list for entrepreneurial skills should be the ability to develop the best income from the most satisfied clientele.

I don't know if I can recommend "learning" to raise from VCs but you're right they should practice all aspects of launching and running a company a few times by doing it.
