It sounds like you're talking more about things that could help middle class people. Very few poor people have issues that could be helped with "pay [themselves] a minimum wage and make up the rest as a dividend".
Sure it'll help the middle class with out current system, but the point was more about how all people should value themselves. Rather than selling your time in exchange for money (i.e., being an employee), you are better off exchanging your value for money. This should apply to any class really.
The reality is different for poor people, but my point was more about "what could be", rather than "what is". Trying to think about it in terms of the current system is flawed, because the current system is designed to enrich people.
If everyone was avoiding tax then the tax would need to rise, or the laws would need to change - this may or may not be a good thing to the masses - but it's certainly not a good thing to the rich - which is why they make sure it doesn't happen.
You got downvoted for saying it but honestly I would expect this philosophy of selling value to apply more to the poor since they're typically not able to make themselves look "employable" anyway. If you're selling a service or a product no one has to know if you attended a top university.
