Miners are the working class of Bitcoin. ASIC miners are the greedy 1%.
The working class are all the vendors and developers that actually do something with BTC.
Miners are more like the bouncers of BTC.
And it doesn't matter if they use GPUs, ASICs or Windmills to do their work.
They have to secure the network, and that's all.
*Disclosure: I don't mine
That's a great view, I also think those people who accept bitcoin payment for their services are the one that back the bitcoin's value
