To be fair, the Greek government fleeced them first in the big scam, at an level non-previously seen before. The lack of trust is understandable.

For somebody who is not so familiar with Greek history: What are you referring to here? What was this scam you're speaking of?

Your contention is that high tax rates lead to low unemployment? I feel like this is an easy hypothesis to test with data.

No, GP is referencing the Greek financial collapse and accompanying austerity measures. They made no reference to the tax rate being high, and even if it was, tax evasion to get around that is unsupportable.

I also highly doubt it’s an easy hypothesis to test. It’s not like you can set up an experiment. Good luck linking correlation to causation given the highly unique conditions in every country.
