I don't know if it's a "plan", but it's definitely a rigidity and "it's our way or the highway", because they can afford it.
The current measures are beyond stupid. They've crippled the country's economy, shut down a large majority of businesses, made the climate hostile to new businesses, and generally ensured that the country doesn't recover.
I don't think we've still seen the worst of it, because the economy has shut down almost completely, and it's still getting worse. The effect of this much deterioration on such a large system will take years to show, and what we're seeing now are the results of policies five years ago.
I'm pretty confident it will get even worse in the next half-decade. Very much to blame for this is the leftist mindset of the average Greek, who thinks "bosses are the devil" and that making the country friendlier to entrepreneurship and investments is anathema.
