You're digging deep, I love it! Thanks for sharing your thoughts. Indeed your mention the need for basic needs to be met before sharing, and has merit. We can't share abundance if we ourselves are lacking.
I'm not sure if fair share is sligned with current economics and politics, although I wish it were! Yes, fair share is vague and can be a bit tough put into practice. For me it speaks to an ethos of interconnectedness and unity, one that redistribute surplus doesn't quite express as much for me. Great thoughts and input!
Cheers man! Keep up the good work ;)
