We need to define a few terms - I am afraid the word "Capitalism" has gotten a pretty bad rap as of late and I wish there was a new word, perhaps "Entrepreneurial" - I'm not sure...
The fact is, the mom & pop corner grocery store where "Mom" and "Pop" are two people in the community who are providing a needed service and goods in exchange for money so that they can live is capitalism. Does anyone see a problem with that? This has a particular meaning to me because my parents were mom & pop, and I grew up working in that store.
No, the problem stems from the cancerous, uninhibited, and politically modified version of capitalism we see all over the world today - where bankers, lawyers, politicians, and power-brokers have turned it into some sort of monster. A monster that is given "rights", "privileges", and is actually listed as "a person" (corporations) to protect those who engage in it. This layer of "protection" is the problem.
In real capitalism, mom & pop bear the brunt of bad financial decisions. Not so in "crony-capitaism" where, if the CEO makes a terrible decision, they get a "golden parachute" of millions in bonuses, instead of being kicked out the door and thrown into the garbage filled mud-puddle out behind the building as they should.
Socialism and it's evil twin brother Communism makes the state the "Corporation" and is just as rabidly wicked, if not more so than the fascist mix of politics and aberrant capitalism we have in the US. All of these systems grow like cancer, and they all steal the vital essence from those who are on the "outside". Socialism and Communism do it at the point of a gun, while crony capitalism simply takes what is yours through incessant taxes, fees, and driving out the mom & pop establishments as they replace everything with mega-big-box-supercenters, and online monopolies. When these businesses start using their power and influence to change such things as the free flow of information, shape the news, and use what amounts to surveillance techniques to target advertising in a manner close to hypnotic suggestion....well, Huston, we have a problem.
If there is some exchange say, a little bud for a little sacrament (and the fact is they are both sacraments) I would think there is no issue there - but that is a personal and spiritual thing that has to be within the persons doing the exchange. And in fact that that is probably true with all exchanges - if done at a level of personal mindfulness between the parties. But when the whole focus becomes the exchange, and those who control the process use power manipulation to change structures in society to enable them to dominate an exchange environment, then we start seeing the shenanigans we observe all around us now.
Ok... rant over.
