Inasmuch, your comparison is completely wrong.
Thanks for trying...
I'll take this one.
Capitalism's "core beliefs" are left up to the market.
An individual who ignores the sacrament of "giving value" that the market demands will be found for the charlatans they are and excommunicated.
(or sit in jail next to the Enron boys)
"Capitalism's "core beliefs" are left up to the market."
And "the market" consists of each individual involved, with their judgments being made by personal interpretation. Inasmuch, there are no set of core beliefs in capitalism. Certainly, there is success and failure based on, as you say, giving the customer acceptable value for a service/product. But value is not a finite thing. I think its ridiculous to spend $4,000 for a Super Bowl football ticket. But, obviously, many other Americans wouldn't agree.
