I would agree with greed but push back on capitalism. There are many ways to be a capitalist. Greed is a common choice, but there are more humanist approaches, too.
From your example, Craigslist is itself is a capitalist institution, making >$100mm/year. Patagonia, Wikipedia, King Arthur Baking Company, Darn Tough Socks, Lodge cookware, are all capitalist too.
I think it's important for entrepreneurial-minded folks to have positive role models – it's possible to develop wealth for yourself, your customers, your employees, and your environment, and to do so with respect and dignity. In fact, a well-operated business is probably the most effective vehicle for having an outsized impact in your community, so defined.
