Earlier quoted context omitted.
If capitalism cares about anything, it's economic growth. It's unclear to me how half-assing two jobs is good for economic growth.
If you perform well enough that your boss doesn't notice, clearly it's providing the value you're getting paid for it? And getting 2-3 jobs out of a person is a multiplier to growth in theory, since they augment more other workers labour.
Let's assume the goal of capitalism is economic growth. The fact that you can hold two jobs while doing no work is not evidence that your actions are helping either of your companies, or the economy, grow.
