$25 a week on groceries in 1997 is around $50 today based on currency inflation, not even accounting for purchasing power. That could easily make the difference between a nutritious diet and one that leads to chronic health conditions for people living paycheck to paycheck. In 1997, the average weekly expenditure on food per person in the US was $34. You could probably have survived off of $15/wk for food back then and maybe find an extra 2-3hr of minimum wage to meet your $25 investment, but it wouldn’t have been pretty.

Fun fact, a $25 steak today in the US cost about $8.50 in 1997.
