While that is certainly true of a lot of them, that is not true of all of them. And historically many of the best inventors in US history have died broke. There are a number of differences between amazon and tesla, none of which is in TSLA favor (more capital intensive, not just facilitating sales from other sellers, fewer adjacent markets to get into and at a higher capital cost, etc). There are indeed scenarios will TSLA becomes very profitable, which is how the stock is currently priced. There are also many scenarios where it only becomes marginally profitable and ones where they go bankrupt.
I said men of vision, not inventors.
“fewer adjacent markets to get into”
Obviously you don’t understand Tesla and Musk.
“more capital intensive”
LOL! Amazon spends every extra can’t on capital expenditures.
