Perhaps they are getting health coverage. They probably wouldn't think of it as a perk. Perks are usually things like private school tuition for children, company cars, free air-fare home every year or two, tax preparation.

Though sometimew when people come from places with universal coverage, they don't realize how important getting employer-provided health insurance can be. And if there are any pre-existing conditions, it could be impossible to get coverage.

Did you consider applying for an H-1 visa of your own, or did you think you would be allowed to work on your husband's visa?

I'm curious about the visa. If she has qualifications for an H-1 herself, can she enter as a spouse, look for work at a company willing to sponsor her, and applly from within the country?
