The term crab mentality refers to the behavior of crabs in the bucket or pot who try to seek freedom. The crabs could easily escape one after another but they pull down each other and prevent anyone from escaping and in the process collectively suffer suffocation and death. The metaphor when applied to a human situation refers to the mentality of an individual or group that endeavors to pull down literally, any person who reaches for the heights of success. Less successful individuals with selfish and constricted thinking consciously attempt to pull down those who are on an upward scale. The crab mentality approach basically subscribes to the idea “I can't have it so I’ll not allow you to get it.” 

Crab mentality is something that can be found in all segments of society. Even charitable and religious institutions fall prey to the malady of crab mentality which can wreck its reputation in society. 

Filipinos call it crab mentality. A lot of Filipino just don’t like it when someone has a better life especially if they live next to their house that they can see them often. In our day to day life in the Philippines We have encountered many Filipino who is like a black hole trying to pull everyone they can into a dark place that represents; sadness, depression, and drama but even with that I am still not so use to it and I am not like a black hole. When someone starts talking and pulling everyone down by making a bad picture of anyone they hate (just because of the fact that they are so jealous of the way they live or the way they are) I talk back and my words tell them that I am not into their game – and it is like I push them out of my life.
 “crab mentality” has become a norm in our society to a point that we hardly even see it as a bad thing anymore and those who are against it are considered not sociable and unfriendly. People having a crab mentality are all the time trying to bring their opponent down. These are the people who cannot do much to improve their own status or achievement. Instead, they try to thwart the attempts of those who aspire to move up the ladder of success. 

Based on my research, the Philippines is a 3rd world country so more than half of its population is not well educated so as expected much of its populace is not well educated enough to live in harmony with other people in a less destructive way.  As We see it –  it takes a good education and some mental level for one to know how to realistically analyze and criticize the culture and traditions one has the experience and live with for the rest of his life.

There's this quote saying, "Pulling someone down will never help you reach the top." So stop the crab mentality, just be happy for what they are now and focus on yourself so that you can be successful like them, do not compete with others instead help one another to reach the top.
