Between the socialists years, 2006-2010 they've spent so much in consume programs that we will be paying for that many years. We're lucky that we have euro, but the proof is unemployment is hight as crazy every year and there are no signs of investement. People also changed mindset from savings to spendings, and now they are demanding more money from the goverment for anything. Please check also Chile, they had couple of programs made by Bachelet, they all failed.

That's a weird argument, given that they appear to have run a primary surplus in those years: https://tradingeconomics.com/spain/government-budget

I agree that there was a massive mal-investment in much of the Eurozone post 2002 (I'm irish and remember this well), but I don't really see how this maps to socialism/socialists. Can you clarify?

It is not. During Zapatero's we had the worst crisis ever, now we have covid's and Sanchez ruling agenda: money spent on gender, progresive things and not in real infraestructure. There's a sort of basic income done, and it is not even working.
