Compared to more equitable economics where the baker gives the mechanist bread to fix the milkmans car who gives the baker milk, and each of them is using cash received from the other to provide goods for their wants and needs, is much more tantamount of a functioning economy than loans, especially when investment money seeks the safest of avenues for returns, thus the vast majority of potential entrepreneurs are out of scope of getting the money anyway.
