I don’t quite understand, if even the contribution margin of an individual driver is negative (before fixed costs), then I don’t see how this model can become viable in the future.
My understanding is that contribution margins are obviously positive (Uber gets at least a half of the trip fare on average), but there is also a cost of investment in engineering and in low fares (which buy market share), that have not yet been covered.
The viability of the business model, thus, comes from the fact that future (quite positive) income from the provided services will continue to cover investments in non-monetary gains, such as brand, market share, assets and IP.
I think we need first to understand what the purpose of schooling is. When you say “terrible at delaying gratification” and “learn or die”, is it something that helps one to be an achiever, or something that helps one to live a happier life?
I think the schools have been long useful for 3 main purposes:
Being a (mostly unsafe) training ground for socialisation.
Producing “standardised” packages of knowledge, which is useful for economy, since everyone knows what to expect.
Encouraging people with a tendency to overachieve to excel at it.
Of these three, only the first one is strictly for the benefit of the student, and even at that it is implemented quite poorly. The thing is, the schools were never designed to maximally help somebody in living a happy life. Of course, we’ve never had the luxury to do that, but as we are progressing further and further from the matters of pure survival, it’s something to consider. And that’s what the linked article is really about.
PS I must also mention that the schools are not at the root of this problem. The culture that judges people by their achievement and success is deeply ingrained in the US (compared to, say, Europe), and the schools and parents simply train the kids to survive in it.
