Good news! The average worker has gone from spending about 25% of their paycheck on food in 1930[1] to about 11% today[2]. This is during a time period where the average worker has decreased their total hours[3]. This is confounded by more people entering the workforce, but the earliest data I can find suggests that we've gone from 58% of the population in the workforce in 1950 to 63% today[4].

(Note that "Food" is "food as a percentage of income", and "eating out" is "eating out as a percentage of food" which makes the chart look weird. This means that the 11% number below includes the cost of the private taxi for your burrito.)
