You are right to be aware of it and to look for situations that won't be so unfamiliar to your wife or present as much of a risk for harrassment.
As the husband of a gal who has been the target of some no-bullshit ogling, harassment, and groping in the workplace; I both understand Avalanche's concerns and am here to confirm their validity.
My wife was more worldly than what Avalanche's sounds like, but encountered such nonetheless in both professional corporate settings and elsewhere; from both religious and irreligious.
Yeah, I don't accept that oogling other people's wives is "reality." I think there are plenty of people with enough respect for the marriages of others not to do it, such that believing that most would refuse to do it isn't out of the question.
It's not the genes that make you stare at another man's wife as if she were yours-it's the lack of self-control that can easily be remedied by a proper upbringing.
QFT.
Self-discipline is terribly out of fashion, nowadays, though. As is self-respect and respect for others.
Contrary to what some folks believe, it is possible to discipline one's mind and thoughts with more or less success.
Bottom line: there are very few places where a gal will be 100% free from undisciplined / poorly raised men. That is a reality. There are ways to minimize such exposure, however.
As to employment opportunities, you might want to mix up the work & education a bit. Does your wife have any post-HS education or certifications?
For instance, at nearby community colleges, you can get a Certified Nurse's Assistant certification for a month's time & $500 (CPR / vaccinations extra). Some nursing homes/healthcare facilities will even pay the way of prospective employees. Something in this field may meet your requirements.
If she already has a bachelor's degree, you can get an RN cert in 15 months at some community colleges.
As has been mentioned, maid service is a fine way for folks with limited skills to make a living.
