It's about the amount of work we do as a society and as working-class people compared to the return that we receive back from it, both directly and through infrastructure and social programs.
We can talk about how certain jobs deserve higher compensation for the amount of work they do or how much value they contribute to society as a whole – but that's an argument that could be made and is made endlessly.
The true focus of antiwork should be to eliminate as much compulsory work as is reasonably possible; this would mean that all the products, services, and infrastructure that are required for modern life should be the primary focus of our labour outputs. But even that would not be enough given our current consumption and production habits; we need to build things to last longer, standardize hardware and software as much as possible, utilize automation to the best of our ability, take advantage of mass production when and where it makes sense, and start treating our products as a canvas rather than art pieces.
I firmly believe that if we changed our world to follow these ideals we would need to work far less, and arguments over how much someone gets paid to do a job would become much rarer. And in all honesty if some people want to start a business or offer a service with the excess of free time they have; let them. So long as they don't have the coercive power of withholding someone's ability to live and participate in society
Do I think doing this would be easy? No. Even if it is possible I'm not sure it could be done peacefully – capital interests are powerful and violent. Higher wages might be a victory for yourself – but a basic income would be a victory for all of us. These should be the goals we're working towards, and we should make sure not to forget that.
