Nonetheless I think they are an exception and, while not impossible, it would be pretty difficult to disrupt the disruptor with a business model based on being more ethical.
In my mind, the mental ceiling keeping us from understanding 'Why more companies can't be like Costco' and 'What's the real value of an Uber ride sans venture capital subsidies' is a lack of understanding of the extensive properties of capital that automation is going to either push us through or bring down on us in a rain of deadly glass shards. I'm not going to wait around for the market to 'get real' and 'focus on companies with actual viable business models' though. 1) The bulk of your portfolio should already be occupied by companies that fit that mold, but 2) The practice of leveraging profitability today for gains in equity tomorrow is going to push through a few big winners consistently enough that it's not going away regardless of the overall consequences. Meanwhile we'll keep asking the same questions that ultimately amount to 'Why does capital beget capital?'
My point being that, in response to the original comment, I think it would be pretty difficult to disrupt the space by "being more ethical."
I've also seen consumer research that shows that a lot of customers, especially younger ones, want to believe that they are buying from companies that have a social mission beyond just getting rich.
You can see this play out in brand fights here.
Apple is either creating great products for creativity (good social mission) or is creating a walled garden to suck money out of everyone (bad social mission).
Google is either solving the world's problems (good social mission), or is sucking up everyone's personal data to better target ads (bad social mission).
Android is "open," vs. iPhone is "secure."
Etc.
