Humans design the system in which the market operates. Obviously one cannot make an appeal to change physics.

We design car and planes just as well with physics.

This is not analogous. You likened criticizing our economy (inclusive of the state of various laws that determine how it impacts people) to criticizing physics itself (to suggest that doing so is unreasonable).

The economy is like a singular, gigantic vehicle we all occupy. It abides certain natural laws (such as human nature, and the scarcity of certain resources), but the vehicle itself is designed by some of our fellow passengers (and its design does not optimize for the things many of us feel it should).

Sure it is. You and other passengers are trying to design the vehicle by ignoring human nature, scarcity, etc. (the physics). Because you are asking yourself why does the piston deserve all the fuel and not the headlights.

This is sarcasm I'm assuming?

I thought implying there was some sort of cosmic injustice when a software developers"deserves" more than a nurse, was some sort of sarcasm. We would never understand anything about the world if we talked like that about for example why does this rock deserves a higher potential energy than that acorn.

I'm not following you. Rocks and acorns are not outcomes of human political will, but our economy, society, and systems, among others, are. Maybe I'm missing something, I'm eager to understand your perspective further.

I hope you agree that human political will is bounded by some natural laws, the same way rocks and acorns are bound by physics. And if you want to do something useful with that political will, you better understand those laws.

Yes I agree with that, but having understood those laws (hypothetically), of which I guess you might be referring to human behaviour, evolutionary principles etc. How can we be sure that those naturalistic foundations could possibly inform the problem of 'what to do now'? Wouldn't be a bit like a mirror trying to reflect itself, or possibly, a fish trying to understand that it's in water?

Understanding the laws doesn't guarantee we'll be able to solve the problem. But not knowing them almost guarantees we will not do a good job.

True enough. At this point I suppose I don't disagree with you, though I've also lost the plot a bit. Hope you enjoy a restful holiday season wherever you are
