Sure, but this being HN, we&#x27;re interested in the &quot;disrupt an entire industry&quot; type business, which are overwhelmingly started by people with good connections and a top university degree that hasn&#x27;t burdened them with unsustainable debt. Not to mention overwhelmingly involving people who have chosen to relocate to the highest cost of living parts of the US to try to get on the radar of VCs, and are foregoing the &gt;$100k a year they could easily command in a regular job there.<p>Obviously there are opportunity costs and expectations associated with starting your own plumbing business too, but    entrepreneurially minded tradesmen or professional services providers not only possess a higher chance of success, but also much more willingness to shut it down and get a job if it&#x27;s not generating revenue quickly.<p>And by the time you get to &quot;half a billion entrepreneurs&quot; worldwide we&#x27;re including people offering goods and services to sale not because of the lure of entrepreneurdom but simply because that&#x27;s pretty much the only opportunity to earn money that exists in their locality.
