The way I see it is that the government wants Greek nationals to use electronic payments for at least 30% of their expenses, to aid tracking.

This does NOT mean the government wants Greek nationals to spend at least 30% of their income.

This is exactly what it wants. 30% before any tax, without counting rent, etc must be spent or you face 22% tax on the unspent amount. :)

That does not compute. How does one prove that 30% of their expenses were done using electronic payments? Submitting paper receipts for the other 70%? It's been tried and it's unfeasible.
