You wife's unemployment would not effect the family based visa petition she filed on your behalf. That visa is based on your marital relationship not on whether you are admissible into the United States pursuant to that visa. The next step after your visa is approved relates to whether you can adjust your status to that of a lawful permanent resident pursuant to that family based visa. This requires you to file Form I-485 with the United States Citizenship and Immigration Service (USCIS). This is the point where your wife's unemployment maybe an issue. Why? Well, in addition to your requirement of showing that you have good moral character and are admissible to the United States, you also have to show that you would not become a public charge to the United States government. Since your wife is unemployed, she can not file an affidavit of support on your behalf so you will have to find someone else or maybe two other sponsors who will agree to file an affidavit of support on your behalf. Basically, this affidavit of support is seen as a contract with the United States government and the individual signing the affidavit of support is promising to financially support you, if you otherwise can not, so that you don't become a public charge and rely on such things as welfare, etc. Keep in mind that if you have a job and you make sufficient enough income where you can support your wife and children, you may not need a sponsor to submit an affidavit of support on your behalf.
