I don't see Spanish politicians making more or less mistakes that other governments in Europe. Spain was one of the first countries to adopt strict measures to limit mobility of its citizens. And according to Google Mobility Analysis [1] Spaniards have mostly complied with it, staying at home at much higher rates than other neighbouring countries.

So no, I don't see a reason to say that its politicians are a joke and that Spanish society is selfish and lazy.
