When you say struggle is as good as success, you are not going to demean it by referring to people who use unjust/corrupt methods. Here you will have to exalt the process of struggle. This you can do in many ways, like for instance.

1. Struggle is a new learning experience even if it leads to failure.
2. Only through persistent struggle can success be achieved.

Here Edison's example should work, wherein on some failure he commented that he had not failed, but had rather had discovered 10,000 methods that DO NOT work. This is a learning experience.

Also struggle here has nothing to do with life. All you have to do is focus on proving struggle equal to success. Remember, words are limited, focus on proving your point through valid logic, don't beat about the bush.

Plus you need to work on your English a bit.

Remember, exalt the process of struggle, do not demean it by referring to instances of corrupt nature.

Also, never use I or we in the essay or the expansion. Use more formal language.
