Walesa was paid €50k to address Libertas launch

Today's Irish Times reports that Lech Walesa was merely a speaker-for-hire at the recent Libertas european elections launch in Rome.

The IT cites Polish media reports that Walesa was paid €50k for appearing at the event.

Walesa is quoted as saying that he accepted the Libertas invitation because he is unable to live off his state pension.
Could that be classified as exploitation of the elderly?

How unlucky for him that he isn’t a retired Irish politician – he’d be swanning about the south of France on his index+ linked pension.
