Proprietary vs. Open Source

It is a bit frustrating sometimes deciding which business model is best, or whether money should be in the equation or a motive at all. There is the proprietary business model where things are owned, and an open source "maker" model where things are not. Both appear to offer income, but the open source model is kind of tricky. One could look at it from a perspective of what model benefits society the most, and it seems to be open source, but it is that true?
