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.
And if somebody makes a shitty car that contains an extra bomb that randomly explodes and kills people we tell them that's a shitty car. We don't blame physics.
