Sure, seeing well-to-do foreigners live an easy life when one struggles in one's own country can feel bitter but the issues in Portugal are structural and predate the 1926 dictatorship. Have you noticed the same handful of families have glided gracefully through the different political regimes? This is not a culture that fosters entrepeneurship or thinking outside the box, and being physically on the tail of Europe does not help. Corruption is endemic and considered part of everyday life, as is "it matters who you know to get ahead." People have become subjugated by this environment to the point they might not even consider it can change.
