Like why this photo filter app boy/girl is super rich + has a lot of free time, and my friend nurse has very little money and works all the time?

Perhaps it's more reasonable to say that providing a small amount of value to a larger amount of people is more profitable.

The world is full of people who simply aren’t capable of providing “value” at scale. Odds are that society gets better outcomes when the few who can do so pursue things like silly image filter apps (and sometimes actually useful things too) over nursing careers.

They rather have negative effects I would say: like a bad impact on teenager's self esteem or something like that.

But yeah, it's our society and it's values :)

In a way, scaling/globalism seems to be working against us.

Let’s also not forget the possibility of highly valuable and highly scalable pursuits.

1. People with the talent to make high-value/low-scale products (e.g. medical imaging) are working on low-value/high-scale products (silly apps). This is similar to how our brightest minds are making people click ads.

2. Apple and the HN reality distortion field make everybody (even those without the skills) believe they can become rich by creating low-value/high-scale apps.

It has nothing to do with the market and everything to do with ease of creation.

Don't underestimate the value and utility of CRUD apps.

Automation and economies of scale has made it much more efficient to produce necessities. Yet society has failed to convert that into allowing the low classes to have more free time. Everyone needs to do some useless job to survive even if there is nothing that needs to be done.
