REINCARNATION IS A TRAP.
Every person has his own set of problems,issues and karmic baggage. What you are facing now is What you have done in the past. Past can be current life or may be previous lives.
You come here on this earth, born to experience but this veil of forgetfulness does not allow us to remember any past life memories. Every fraction of second what we think, we speak and we act becomes our Karma..and we will get back accordingly.You,instead of clearing old baggage,start collecting new and the process goes on. Its seem to be a real trap.
In these dark ages,without proper wisdom its really hard to break this trap so people are just part of it without actually understanding why they are born on this earth.
So understand & work upon your purpose...finish up your job...learn your lessons...and move up and beyond.
