I recommend de friending and blocking your now former friend on FB. Then, you won't see these things. Also, people put up a huge facade on FB. Everyone has struggles and their own issues, no matter what they say or post. Yes, some people are rewarded for poor behavior, but they do have to live with the consequences. What helped me with the whole not fair thing was spending less time on FB and more time with friends and family. I set my own goals and focused on myself rather than others. As my T, and Teddy Roosevelt, would say, "Comparison is the thief of joy." Don't do it!
