I agree moving is difficult - but so is creating efficiencies like Bezos has done. If your social views include the view that life should be easy for everyone, no matter their contribution, then we have a fundamental difference in what is realistic. If that is your view though maybe a better solution would be for those with money who share your view to support those without jobs or working with Amazon (or pay them to not work for Amazon). It is very easy to ask Amazon to change their policies, but that's because it isn't your money. (It's also worth noting that Amazon is not even profitable and runs in incredibly competitive industries. And, for every dollar they have to raise in costs they need to raise in profits.)
Your solution might work but has some concerns. Although the market for unskilled work is very heavily weighted towards companies the market for skilled leadership is very competitive. There is a reason top executives at Apple, Google and Amazon are paid well. Paying 10,000 workers $1 an hour more means $20,000,000 less yearly to spend on upper level talent in a highly competitive marketplace for that talent.
I am pointing out the human respecting nature of the market exchange - that it respects human choice (no matter how bad or good an individuals choice may be) rather than implying the idea that someone else knows what is best. Coercion is "the practice of persuading someone to do something by using force or threats". I have never heard a story of Amazon threatening someone to work for them or using physical force to entice them to take a job. Taxes, military drafts and certain types of crime are coercion - posting on a job board is not.
