History has shown definitively that socialism causes more human exploitation and injustice than capitalism does. Capitalism is, hands down, the lesser of two evils.
We don't need evil of
any kind. Getting into a who is less or more evil than another is pointless. Perhaps even evil.

The people being capitalized on (I assume you mean employees)
No I don't mean employees. I mean
whoever is being taken advantage of by someone else and lacks the means to secure a fair return on their energy/material/time/expertise investment. The western lifestyle is predicated on someone somewhere doing the dirty work for pennies per hour. Anyone who champions maintaining huge wage differentials is championing another evil.
Same goes for collectivism in all it's various forms. .
I'd love to see the math equation you worked out on "collectivism". Does me swapping fruits with my neighbour for more variety in my diet count as "collectivism". Why is it
mathematically bound to collapse? As Atash alludes to, a system predicated on fiat money (representing wealth) withh interest is a mathematical anomaly running on borrowed time. The equation doesn't compute, ergo is must collapse like the ponzi scheme it is. I'd love to see the math showing how my fruit swap among equals is a ponzi scheme....
So in other words you would have everybody add value according to their means and avoid profiting from it, effectively giving the added value to everybody else according to their need. That is what socialism is, and far from being entirely new, it's been tried in many places and it has a track record of 100% failure. Ironicly, the chief failure of socialism is that it places higher value on money than on human well-being which is your primary complaint against capitalism.
No, I wouldn't do as you suggest. Socialism is as fundamentally flawed as capitalism (and any other western--ism you care to mention). I would swap things of equal value. This is world away from "
giving added value to everyone else". Thus the value I add is the value I enjoy, as does the person I do business with. We both come away enriched by diversity rather than profit. I don't want or need any central planners to regulate my fruit swaps. A useless idea. Even as all the monies in the world come to be seen as the worthless proxies for value they are, a guava will still be a guava - a contributor to human well being. I'll leave you to convince me of the doom to follow for living outside of a western box...as I enjoy the fruits. I don't fit into any of these boxes.
As a footnote, it is also worth mentioning that
every economic system used to date has a 100% failure rate. How you classify one 100% failure above or below another 100% failure is beyond me.
