Inflation?

 Little Johnny listens to his grandmother as she complains about the high cost of living. 

“When I was young,” she says, “you could go to the store with just a dollar and come home with enough food to feed your family for a week!” 

“Well, Grandma,” Little Johnny says, "that's called inflation. We learned about it in school.” 

“Inflation nothing!” Grandma snaps. “It’s all these dang security cameras they’ve got today!”
