CMV: High-performance employees are often penalized for their superior work while low-performing employees skate by.

I give 1000% at every job. Everywhere I've worked, my performance is "rewarded" with more work and more responsibility. Some of my coworkers, who contribute very little to the team, aren't given the tough jobs because managers know they're not up to the task. At one job, several of my coworkers were allowed to work from home one day a week. It's because no one missed them, and they really weren't much needed to begin with. I, on the other hand, tried to work from home one day a week, which lasted exactly two weeks. I had to go back to the office because I was "too valuable and too necessary to be away." So my reward for good work is more work and less time off. We were all paid the same salary, by the way. Thoughts?

If you can get more work out of someone for free, well...

This isn't a punishment, it's just taking advantage. You interpret it as punishment, perhaps, but for the employer this is just a calculation.

This is about leverage, typically (when no unions are in the picture) employers have all of it if you're not coming to the table with harder to find skills which provide the worker leverage. You can try to negotiate, but of course they may just say no or fire you. Only people who they are afraid of losing will have leverage. If they can replace you with another high performance person who won't ask for more, they'll likely do that.

 You can also work less or say no to increased responsibility if it doesn't come with increased pay, too. Although once they know you're unsatisfied they may replace you with a more easily managed employee who isn't critical of anything.

Don't expect employers to be ethical, lol. Unless you work for smaller businesses, most of the time they are 100% built to exploit you as much as they can.
