No, I'm sorry, it is a myth. Both myself and my childhood best friend grew up in relatively poor, working class households. Yet our families were able to afford to buy NES consoles, games, even a Game Boy later on, SNES, etc.
As a working adult, I have more trouble affording the ever-rising cost of gaming than my family ever did when I was a kid. Inflation has an effect, sure, but being able to have an NES and a whole slew of games didn't set us back THAT much back then. Buying a $400+ console and $60 games certainly does now.
