Instead of fighting for better conditions of workers and citizens in general, left-leaning parties have been worried about pushing propaganda.
Take in account that Franco died more than 45 years ago, and most of the governments since them (and the current one) have been left-leaning (PSOE mostly).
And now, in Spain, the COVID-19 crisis has shown the inefficiency of the government, people are paying more than ever for electricity consumption (in a heat wave), the unemployment is the highest in the last years, and the price of buying or renting a home is high as ever. Thus, the government wants to charge us for the use of highways (already paid by taxes), and reduce the pay for the retirees.
Ideological propaganda (left-leaning mostly) is very much alive in Spain.
