🔬 **Some notable exceptions to that global trend**:
In the 🇺🇸 #USA, the influence of income has vanished, and support depends solely (and strongly!) on education (highly educated ↔ leftist).
In #Scandinavia (epitome: 🇸🇪 #Sweden) it's the opposite: education became irrelevant, and political preference depends only on income (perhaps because they are wealthy, egalitarian countries?).
🇵🇹 #Portugal hasn't changed like the other countries: there the Right is still supported mostly by educated (and rich) voters. (NB: in the 50's and 60's, Portugal was a dictatorship).
🇮🇹 #Italy is the rare case where leftist parties ended up being the parties of the _richest_ segment of the population. I wouldn't read too much into this, though, as the political landscape there during the last decade or two has been a populist mess.
🇪🇸 #Spain is the country where education and income tell you _the least_ about political preferences! There's still the secular correlation “high income ↔ right wing”, but it's very weak today. (NB: in the 50's and 60's, Spain was also a dictatorship).
