Hmm, so 99% of the value you create is being skimmed off by the company's shareholders and management? Have you thought about trying to renegotiate to a more equitable split, like 10%/90% or 50%/50% instead of 1%/99%? Or is that impossible because you're in a very weak bargaining position, like a migrant cannery worker?
That seems like a major reason people might quit jobs like yours and go work for ERP vendors or other outsourced vendors: even if they create less value, they are in a better bargaining position and so they can capture maybe 5% or 10% or 30% of the value they create instead of less than 1%.
