Do the beneficial microbes that live inside me have an "easy life" where they have unrestricted access to everything they want, or do they have to compete for resources like most other life forms on earth do?

They compete for resources with each other. For example, a person with c dif infection may have come about because the c dif out competed the natural gut flora for resources after an antibiotic killed off the less harmful gut bacteria.
