Is $200/month a lot of money when you can multiply your productivity? It depends but the most valuable currency in life is time. For some, spending thousands a month would be worth it.
My butt needs to be in this chair 8 hours a day. Whether it takes me 20 hours to do a task or 2 doesn't really matter.
If you're salaried, you are not a task-based worker. The company pays you a salary for your full day's worth of productive time. If you can suddenly get 5x more done in that time, negotiate a higher salary or leave. If you're actually more productive, they will fight to keep you.
