I won't bother speculating on the origins or nature of this socioeconomic situation, but I think we can focus on the first order things we have more control over.

For instance, be willing to fire your fucking customers. If someone is being a jackass in your establishment, make them leave. If they persist, involve LEO and trespass them.

There is no reason this cannot extend to the software realm. Make sure your customer contracts have some sort of language regarding circumstances for termination. Apple, Google, et. al., have certainly applied this thinking to their customers via EULAs and the like.

There is no customer so valuable that you should endure abuse for their patronage.
