The article is about food banks too. I am from NL, and the first food bank here was established in 2000.
Why were there no food banks in the 80s?
That's because historically this was managed through ubiquitous trade unions and collective agreements. The need for a legal minimum wage increased due to the rise in contract / temp work, and US corporations moving in (notably Amazon whose approach to labour relations has been distinctively american).
edit: replaced "official" with "state run"
AFAIK, all food banks in NL are NGOs.
edit: I wonder if the Tafel date of 1993 has anything to do with the reunification.
