Eh, there's a problem with the "offer." Essentially, the entire political offer, the main parties, all are right-wing.
This is to say that it's a dying democracy as the representatives are less and less representative, since they represent a minority of conservatives and of aspiring rat race winners.
The figure about is not a cycle, it's a spiral, a death spiral. It ends with fascism causing major crises and bad times.
I understand your concerns, by all means, vote for the least evil party, but don't pretend that it's not evil.
The other side of the observation is that politicians consistently concede and compromise to go more right-wing and neoliberal. It's extremely rare to see some political figure go: "oh, yeah? You're going right? Then I'll go left!" No, they keep pandering more and more to the right-wing electorate, to the conservatives. As the masses are no longer represented, they don't vote.
The causes of this are multiple, so I won't get into them. I'd just say that you should understand that the austerity policies that are coming are desirable by all the right-wing, neolibs and far right. The far right just weaponizes austerity against the "bad minorities", that's the early fascist regime.
