How do I politely tell my friend I don't want to be involved in the pyramid scheme they want me to be a part of? [I Need Advice]

They were looking out for me, but the business they want me involved in seems dubious and illogical. I don't have a job, but the way this mentorship program seems to work is you have to recruit people to get to the next level, and the more people you bring into it the more money you make, and more entrepreneurial advice they give you. I don't know what to do.
