Mama
I never understood how Mama was able to afford a house on a maid's salary. In addition to being a single parent, raising two kids without support from the custodial parent, this seemed unrealistic even for TV.
WH was based off the film Cooley High in which the Mama character in the movie was raising two kids living in a small apartment. I guess Norman Lear, or whoever produced this series didn't want to approach the low-income, living in the Projects scene like it was done with 'Good Times'. But the single mom supporting her family by scrubbing toilets but able to keep up with the expenses of running a house, just didn't seem real.
When life gives you lemons, make apple juice and let the world figure out how you did it!
