They made sure that they had a political foothold in professional or amateur clubs and associations, be it sports, business, or simple leisure activities. It didn’t matter. What mattered was that they signed up to ND or PASOK.

But that’s over, now.

The two-family party system, throttled by the economic crisis and austerity measures, has largely given way to extreme right and left-wing parties.

At the last election in May, ND came first and received the 50 seat bonus. But even together with PASOK, its long-time rival, it still wasn’t strong enough to form a government. Hence, this Sunday’s new election.

Alexis Tsipras, the leader of the populist left-wing Szriza party that won 17 percent in the May elections may become head of the largest party on Sunday. Then what?

Clearly, he will be automatically allotted his 50 extra seats. But unless the opinion polls have gotten it all wrong, those extra seats will not give his party a parliamentary majority. He will have to form a coalition. His options for coalition partners are limited.

Tsipras has made it clear that he had no intention of withdrawing from the euro. But neither has he any intention of sticking to the austerity package. In which case, the EU and the IMF have threatened to cut off all further payments to Greece.

From their perspective, it would be better if Greece’s old parties made a comeback. At least they are, in principal, committed to keeping to the austerity measures.

But do they have the political maturity to see reforms through?

Look at what happened in April.

In the throes of this financial crisis and while the austerity measures were badly hurting ordinary Greeks, ND and PASOK hurriedly voted through a bill that grossed them an extra 29 million euros in state funding. They declared it an advance on payments they would be due to have received later to finance their election campaigns.

Most opposition parties decried the payout. It was “a provocation” of voters who were trying to cope with the austerity and economic crisis.

In Brussels, Guy Verhofstadt, leader of the liberal group in the European Parliament and former Belgian prime minister, was furious. European taxpayers, he wrote, were funding Greek political parties.

"The cost of politics in Greece is a scandal,” Verhofstadt wrote in a letter to Jose Manuel Barroso, president of the European Commission.

“Pasok and New Democracy are responsible for all the structural problems of Greece and like leeches they have been sucking out millions of taxpayers' money", he wrote.

Verhofstadt added that in 2010, the political parties in Greece were one of the highest funded in Europe as a proportion of tax revenue (0,14%). That was 7 times more than in Germany (0,02%).

"Why should we continue with the second Greek bailout package if the two largest parties in Greece do not show any signs of changing the system? It is not acceptable for the European tax payer to effectively pay for the 'recapitalization' of the Greek political parties," he added.

Little did Verhofstadt know that ND and PASOK are broke, which says a lot about their ability even to administer their own finances.

Despite all their years in power and the way they entrenched themselves in a system of patronage and clientelism, they can no longer pay their staff. They owe the banks 250 million euros.

What does that say about their ability to administer billions of euros in EU and IMF bailout funds?

No matter which party wins on Sunday, Greece’s next government needs to achieve a giant leap in political culture if it is to make the Greek economy more competitive, the state more efficient, and civil society more vibrant.

But how likely is that?
