election to pay CPP contribution with foreign income?

Since there was an annoying reply to my question, I rewrote the question. PLEASE advice me if you can.

For a resident of Canada, Is election to pay CPP contribution a wise move? Or just save money by himself?

What's the advantage of CPP compare to RRSP, or other saving plan?
Thank you!

What country are you working in? If you are an employee or if they have their own version of CPP, you can't self-contribute to CPP.

Are you sure you are still resident of canada?

Just want to know for general situation, if CPP better than other pension or saving plan.

Let's forget about answering your question....
