Is there a home business that is not a scam?

Yes and no.

If someone is offering you the opportunity to make hundreds of dollars a day at home, that is probably a scam. Like pretty much anything you see advertised on line or in your email's junk folder.

If on the other hand the person with the home business is just selling a good or service, and not asking you to invest, then it's probably legit. Like a day care, or someone making and selling quilts or cookies.
