That's a very interesting scenario and for me, there is no right or wrong answer. I would never label you as scumbag because the compensation structure was setup by the management team partially allowed the scenario to happen. It's a pity because it sounds like you have a lot of potential and your skills can be better used elsewhere to improve other areas of the company. Your managers should be aware enough to realize this.
Of course, on the other hand, you could also take the initiative to try to help your coworkers improve themselves and their productivity. Time spend playing games on your phone or reading reddit could've be partially used to help encourage other members on your team. Maybe the compensation structure deters you - but I am sure some if not all of your coworkers would really appreciate your help (technical or non-technical).
