Syriza and Independent Greeks (ANEL) aren't the ones that built the debt, in fact if anything the have the greatest chance to bring down the debt and stabilize the economy.Greece needs to keep funding the fakes and phonies who are drawing the public trough, they are dependable Socialist voters!
Panhellenic Socialist Movement (PASOK) and New Democracy are the two parties which built up the debt, hid figures, and were quite corrupt when they ruled Greece on and off from the 1970s to 2014.
Ultimately though PASOK is the party that forced the bailout and messed up the Greek economy, so with them out of the picture Greece has a chance to recover.
So Greece rather than 'funding fakes and phonies' has done the reverse of that by booting out the establishment, even if on the surface Syriza is far-left.
Greece's current gov't spending outstrips its revenues. There is little reason to believe revenues will be going up any time soon and new foreign loans are about to dry up. Without real cuts in spending - something Syriza adamantly rejects - the future of Greece is one of severe austerity. The new Drachmas will literally be worth less than the paper on which they'll be printed. BTW, default does not wipe out the debt. Nice work, guys.
