Your descriptions of free enterprise as opposed to corporate capitalism are very close to my own. Corporate capitalism is a locomotive. It runs on a track. If you insist on standing on the track, you will either have to get on the train or get run over.
But if you step off the track, the train continues on, not noticing you. You are at liberty to live a life you choose, make, and (within natural limits) control.
Of course, this involves hard work, stubbornness, and (like everything) luck. You have to really want it. You have to accept responsibility for yourself and your actions. You have to think. You have to persevere. You have to keep your head down and accept anonymity. You will never be on the cover of Forbes.
I know enough people who are doing this to know that it can be, and is being, done. People who choose to do this are, though the ones I know would reject the term, to my mind, real revolutionaries, revolutionaries of the heart.
They make me think of something Ursula Le Guin wrote in The Dispossessed:
“You cannot buy the revolution. You cannot make the revolution. You can only be the revolution. It is in your spirit, or it is nowhere.”
This gives me a teensy bit of hope. The hope that the spirit of individual liberty still exists and lives in the determined spirit of those who choose to say NO! and get on with living life as they desire, as they see fit, as best they can.
