I am a programmer who can't get a job at Facebook. Do I take a job at X Corp paying $5/hr, or do I spend 100 hr writing an app that will only gross $500? Sure the app COULD gross more, but in my low talent niche, it is well known how much revenue MotoX Flashlight can generated. Should Google be allowed to publish my app, knowing it will never clear more than $500 revenue? If so, why shouldn't they pay me $600 (still below min wage) to write the app for them?
