I don’t think people should have to care. They are customers. They want to buy things and have them delivered for a good price.

Why is the consumer or shareholder being asked to solve a legislative problem?

Buying consumer goods shouldn’t be a political statement. It’s just ignoring the actual problem of insufficient legal protections for workers.

If Amazon can orchestrate a scheme in which they subcontract deliveries to absolve themselves of the responsibility for employee health and safety, that is a legal issue, not a “I gusss I shouldn’t order dental floss off Amazon” problem.

Political action is difficult, and takes a long time to have an effect. I can't do anything about the situation in the USA anyway.

I can boycott Amazon immediately, with only a small effort.

I encourage you to do both.

If I owned a hypothetical number of actual slaves that allowed me to give you a great bargain on cotton, no matter what political action you take while you use me as your sole supplier of cotton, it will not be effective. All of the alternative sources of cotton will gradually go bankrupt or convert to my model, and I'll use the money you send me to shut you down politically.

It's almost as if low prices and fast shipping are what people care about.
