“It is not from the benevolence of the butcher, the brewer, or the baker that we expect our dinner, but from their regard to their own interest,” wrote Adam Smith, but it can’t hurt to ask:
“We address ourselves, not to their humanity but to their self-love, and never talk to them of our own necessities but of their advantages,” continued Smith, about the butchers and so forth, but perhaps with tire and windshield and suspension manufacturers talking of one’s own necessities goes over better?
I think if I ran an auto-parts supplier I would not be all that keen on helping a $50 billion company run by an eccentric billionaire become profitable. Like, right now the situation is that the suppliers are profitable (I hope!) but not $50 billion companies run by billionaires, and Tesla is unprofitable but a $50 billion company. Who really deserves whose charity?
If the suppliers sacrifice their profitability and give it to Tesla, I do not see Tesla sacrificing its market cap and giving it to the suppliers.
