Maths fails when humans that use it deliberately and systematically against people.

In other words how much are you worth ? This starts you thinking... It's just an opinion...

Often systems (by people or people higher up in position) deliberately devalue people so they do not compete with them and stay low... systems don't want to give to people and short-change them instead.

I could value you less than someone else even though you do more hours and less work.

Material is valued more than mental-health.

Happiness is hardly valued and could be measured as the judge for changing jobs for the better.

Devaluing nature, for example; asking yourself "how much am I worth" means you can check yourself and find any value is incorrect.

Only because food then we need X number but it's nearly unneeded and manipulated as a system 'could;' make sure ALL people is fed and watered" rather than pay more and more for little and little..

Governments can value things that favour itself- so that is the biggest danger. It could make some people work more than others typically teachers, teachers, doctors etc....
