Why do some people work hard all their lives can only be said to be caused by the continuous accumulation of all the tiny factors in life. Many people turn a blind eye to the overall situation and then complain about life. No one can control the negative news you mentioned, and there are still many people whose time is even more difficult. This is nobody's fault, and you can't expect others to change it. If you have that heart, you should do your best to help change something, instead of complaining and asking why, there is no reason.
About fairness, this is just a word invented by people. Where can life be absolutely fair? But the existence of unfairness does not mean that there is something wrong with life. Maybe it's just that people look at things from different angles. A coin has two sides, good and bad. This is your subjective opinion. A blessing in disguise is a blessing in disguise, but it is natural to cross the bridge. On the contrary, some people say that they are prepared. You don't have to force yourself to look down on these things. Maybe in your life experience, when you look for the answer in your heart in the books and movies you read, you have grown up unconsciously, which is not necessarily a good thing. Why run away from it and avoid it?
Maybe we live the same life over and over again, do the same things, live the same life over and over again, forget it. Perhaps the best way to escape is to live today. If you think there is something wrong, strengthen yourself and try to change it with your own strength. It's no use complaining, and your heart is not artificial. Live the most meaningful life, and then leave peacefully.
