Sort of a rant, I'm so annoyed by this girl!

A coworker of mine works part-time, 30 hours a week. She spends a lot of her down time at work searching the internet for some new disease, takes time off work to bring her fiance to the dr's office for this 'new disease' he (or she) has, and then writes letters to social security about how her fiance needs disability because he can't work.
Her fiance doesn't have a job other than hauling junk (which pays cash so he doesn't have to report to the government, also mind you a very physical job that someone with a disability wouldn't be able to do).
When someone brings up a job opportunity for him it's "oh no, he can't work because then we'd lose our insurance (meaning they'd have to pay for it vs getting it for free), and they'd have to pay more than the $125/month they pay for rent (salary-based).
Sooo annoyed by people that abuse the system like this, but still have the newest smart phone and name-brand clothes.

He and she are perfectly capable of working, but are content on letting the government pay for everything, and are trying as hard as they can to get on disability.

It makes me sad for the people that actually need help! And it makes me sad that she doesn't WANT more for herself, a nice car, owning a home, etc.

Do you know anyone that abuses the system like this? Is there anyway to report it?
