Used to in the USA. when I was in school lunches were all made from scratch from a full time kitchen staff. Guessing today the MBAs have figured out how to reduce costs by automating and centralizing food production so that schools only need to heat-up lunches and thus reducing tax burden. America has highly developed industrial food manufacturing and supply lines and a public willing to accept it. Just different values about how food is made, priced, and brought to market.
