Human nature under capitalism isn't human nature buddy, and when you have strong unions with democracy and collective ownership, it works, As shown by examples in history.
Proving only that your neither know history nor understand human nature and you still haven't explained how you intend to "peacefully" transfer control from individuals to unions.
I do know history, and we wouldn't have survived if we were inherently greedy, my position is, human nature is a silly concept, but if we're going to go with it, the actions and inherit greed of humans you talk about is thrust forward due to capitalism and other systems encouraging exploitation, not wanting solidarity. I don't know how, I'm opening it can be peaceful and democratic..
"Opening" it can be peaceful and democratic? Really?
So how does one peacefully and democratically confiscate the wealth of American individuals and transfer it to your union buds? You 're gonna need a plan because it is at the core of your POV and the Americans I know aren't just gonna say "OK, Sport!"
BTW, Kumbaya is a silly concept and greed (or capitalism if you prefer) "in all of its forms; greed for life, for money, for love, knowledge, has marked the upward surge of mankind..." - Gordon Gecko,
