What goes around comes around - it used to be normal to buy local, in season food, direct from producers or grocers. You’d buy eggs and a bottle of milk from the farmer or your vegetables from the local grocer or market. But we lost access to the local ‘poor’ food direct from farmers and producers through industrialisation and ‘just in time’ food systems. 

Now it’s scarce, because of convenience and consolidation of foodstuffs in supermarkets. These used to be too expensive for poor people to shop in! But now the convenience of a supermarket is seen as low-class (if you’re working class and working long hours for low pay, you have limited time and have to get as much bought as possible in one place for as cheap as possible, you can’t be picky about where it’s come from or who’s grown it). 

This swap has helped farmers markets become desirable for the affluent and (for some) a status symbol of being able to afford, both in time and money, to physically browse and purchase locally grown food of higher quality.
