Im wondering about the much bigger implications of a grexit.
People on the "soft left" aka Keynesians like Stiglitz, Krugman claimed that greece's problems wasn't that it spent too much but only they weren't allowed to spend more and if they spend more then "their problems would of been gone compared to if they done austerity". While totally ignoring that for the past 30 years the greek state has been in a state of fiscal expansion through foreign borrowing.
Although the borrowing and spending did boost the greek economy a lot of it didn't flow into investments to create industries needed to repay that spending but as an clientism in return for votes.
For one of the many examples.
Greek pensions were very generous because instead of it being employer+personal contributions the state actually subsidized a lot of it. Even in 2012 despite cuts the greeks were very generous in pension spending as % of GDP.
http://lolgreece.blogspot.com/Basically the greek economy was the equivalent of a rent seeking oil rich arab state but instead of oil rich was borrowed wealth rich due to large amounts of borrowing. And they created a welfare state paid not with their own industries which of tourism and shipping would be unable to afford such expenditures on its own.
But back to Krugman and Stiglitz there has been a steady decaying of keynes original ideas. Keynes said to run surpluses in good times. Greece actually kept spending even in good times.
And Krugman and stiglitz said that governments should just keep spending "to boost the economy" but have backed away silently. especially when greece spent so much money but ended up in a crisis anyway by overspending.
And the
final nail in the coffin is when they advocated for greece's debt to be forgiven. If spending more and more money didn't save the greek economy then perhaps the Soft Left or basically Keynesian-ism don't exactly hold all the answers/theres no one size fits all solution/its complicated.
Perhaps its time to stop treating keynes like a god and realize that theres no easy set of solutions to all economic problems.
