The document discusses several factors that contributed to Greece's debt crisis following 2008:
1) Structural problems in Greece's taxation system led to significant lost government revenue.
2) The Eurozone's structure disadvantaged peripheral states like Greece and benefited core countries like Germany.
3) Greece had a large current account deficit and was vulnerable to the effects of the global financial crisis, requiring bank bailouts.
While the Greek government was not solely responsible, issues with tax collection and long-term debt exposure increased Greece's vulnerability when economic shocks occurred.
