Are politicians only motivated by money?

No... Many are rich be politics... It's the power that goes with politics

99% of them

Politics is a cash cow unless it is properly monitored and money carefully put out of reach of the greedy. I you made it illegal for any politician to leave office with more than he came in with and pay him minimum wage to keep the greedy from getting in.

And power

Many are, but not all.

No: it’s power

No. But you're not going to talk ideology! They care about politics! They plan generation after generation, with think tanks and policy papers! You have no politics. The masses hate those like me with coherent ideology. The mainstream and its oligarchy spend trillions keeping politics away from your view online. The algorithms suppressed politics for over a decade to make progress there impossible.
You like saying it's mental illness or corruption or money. You like falling.
