I suppose it depends on what is the collateral for the loan. Technically I think you could take out a business loan where the collateral isn’t the business or its assets, but practically speaking what else would be used? Is the founder going to use their own personal property as collateral? Almost certainly not if they also have to share the profits of success.

For that matter how would banks work? Anyone working at the bank would share in the profits of loaning the depositor’s money? That doesn’t seem to follow the spirit of “sharing in the fruits of labor”. The depositors are the ones laboring to earn the money, why should someone working at a bank get to profit from the interest earned on the fruits of their labor?

A solution to that would be the depositors earn the profit from loans, but then we’re just back where we started. The more you can deposit and loan, the more you earn and labor becomes less and less significant. Also, what of the banker’s labor then? Are they just paid a wage and have no share in the profits of the loans? That sounds very similar to a typical company today where the shareholders reap the profits from wage workers’ labor. Will bankers be the working class of this new society?
