While income taxes are low for the majority ( the salaries are low anyway) the indirect taxing is the way the Greek Goverment managed to recover.

The prices of everyday goods rose (sometimes more than double) and the profits from VAT(24%) with them.

High duties on fuel + fuel price went up, combined with rent prices (living far away from your workplace) => longer work commute, bad infrastructure and older vehicles ( no money to buy a fuel efficient one when you are poor)

Liberalization of the energy market forced by EU which lead to extreme prices. (new companies that don't produce anything got in the middleman position with only goal higher profits)

In summary, everything has been and continues to be done at the expense of the majority (low-wage earners), while making them even poorer.
