The main comparison is how long do u need to work to pay for meal ...in America u need 1 hour at most 1;30 mins to pay for a $10 meal ( which is far higher quality than #500 food here ) if u earn minimum wage

In Nigeria u need 5 hours to earn #500 to feed if u earn minimum wage ..American standard food would cost u minimum of 3000 that's 30 hours to pay for a standard mean in a decent place if u earn minimum wage
