I wrote a snarky and unconstructive reply to you, but though I don't think I was wrong, I deleted it to try to be more constructive.
In this thread, you began by replying to a comment ultimately making the point that the OP commenter brushed off academics unjustifiably. Your reply suggested that the relevant comparison was between a professor whose position is secure and a startup founder in the early throes of trying to gain traction and stability. This was the clear essence of your point -- that somewhere somebody suggested, through such a comparison, that running a business is easy, and that this is wrong.
That comparison is obviously not relevant, especially since the slightly broader context is this article about "capitalist cowboys", i.e. people like James Duke. Duke was born into money and the tobacco business. He did not risk everything for his business. If his cigarette company went completely under, he would not have been destitute. People like Duke are relevant for comparison.
The reference in OP's comment is a common one, to "academics" at large, and is uselessly disparaging. Beyond user "lower"'s point about the skills needed in academia being comparable to those needed for business, we should note that many academics, especially in business schools, have themselves literally been successful in industry and business (read outside of academia). This is a proven way of getting a faculty position at a business school.
I think your point doesn't stand. But you are right that starting and having a business is a nuanced, often risky... business.
