Are Portuguese only complaining about the economy?

I don't think so. They are also widely complaining about corruption.

The truth is Portuguese feel corruption crippled their economy and takes a large part of the blame of the current economic situation. More than that, I guess most Portuguese aren't seeing significant work is being done in this area - actually, the fact the Governmen is failing to deal with the corruption charges to some of its  members only adds to that feeling.

The huge number of redundant highways (with very heavy contracts behind them), the shady connections to private universities, the number of public works done by municipalities without any reasonable benefit (vs the cost), the planning for high-velocity trains and airports, the schemes with European funds that were diverted from meaningful investment, the unreasonable benefits for public leaders (members of parliament, managers of public foundations without any meaningful work done, sub-secretaries of state and public consultants with no curriculum but being part of one of the major parties)... and the list goes on and one... I feel Portuguese are really sick of this - and it is at the root of their protests.

Corruption is a must tackle in this period of turbulence!
