The one show that immediately comes to mind is The Middle. If you're not familiar with the show, it focuses on a working-class family that's struggling to get by. The father, Mike (played by Neil Flynn), is a good, hard-working man who loses his job. He later takes a last-resort job as a truck driver. Meanwhile, the mom, Frankie (played by Patricia Heaton), works as a car salesman (or saleswoman rather). Obviously not the greatest job nowadays.
While the parents are working, they're also supporting three kids, Axl, Sue, & Brick, who's school activities consume almost all of the time off that they have.
Another show that relates to the economy (& gender roles) is Desperate Housewives. In the past, the female characters on the show have been portrayed mostly as the 'moochers'. Having the husband who works & the wife who stays home tending to the kids.
One change that has occurred in the newest season is that Tom & Lynette's roles have changed. Having five kids already, Lynette finds out she's pregnant, again, with twins, again. She had established a well-paying job and is the main bread-winner for their household. When her boss finds out that she's pregnant, he fires her, wrongfully, and Tom must take over as provider for the family.
