One of the things complaining is not, is a passive noting that certain things are bad. It’s way of doing something. Rational complainers complain about thing they can affect, which tend to be relatively small scale and close to home.
Another thing complaints about inequality are not is a substitute for threatening or grabbing. Those who have the power to grab, grab, those who can issue plausible threats do so. Complaints about inequality are part of a process of rationally discussing resource allocation, and can lead to reallocations that are preferable ethically or in terms of efficiency.
A successful argument for reallocation involves multiple factors, including the extent of an inequality, it’s tractability, and the benefits of changing it. Natural inequalities, like looks, tend not to be tractable. Opaque acquisition processes make it harder to counterargue that resources were fairly acquired. Emergency situations can tip the balance of argume.nt by creating urgent needs.
