It is, but someone working 60 hours a week often just wants to do something easy and learning new skills takes effort. I myself have been learning to cook more but its still a big time commitment and i try to plan around it to reduce spur of the moment trips to the grocery store to save on my expenses, instead trying to shop when I'm already in the area for other things as well. I also try to shop sales and expiring soon reductions which further reduces my options of cooking for a given week. Its a big balancing act of time, energy, and budget, and as the stomach starts growling people throw the budget portion out the window to save on time and energy by buying fast food.
