Everybody's effort is needed in order to combat crab mentality.  This is happening worldwide.

We need to stop bringing each other down because of our pride and instead lift each other up.
We have a lot more in common than we think and we all are working towards success in our lives.
Together, we can reach new heights by helping one other instead of trampling over each other's goals.

Recognize that it's just a mentality. Rise above it.

Start with yourself

You have to first help yourself before you think about everyone else. Once you have learned to deal with your own tendency to give into the crab mentality,  you can then start to help others.

then the community

When many individuals realize that they can help build up others, people begin to help others in their community
 grow and improve.

and finally, the rest of the world.

People helping other people.
That's what can bring about change in the world. When we're confident that we are for each other, we can be unstoppable.
