Profits are better than wages for two reasons. The first is, you can make money when you are not in the room. The second reason is a bit more curious:
You can sell a profit making ‘machine’, while you can never sell a wage. This means that every dollar you earn from profits has a natural multiple built into it. If you earn a dollar through profits you may be able to sell that dollar for 2, 3, 5 or more than 10 dollars.
In the end, it’s the simple difference between carrying buckets of water, or building a pipeline directly from the source.
