Yes, the matter is absolutely realistic, in this political life, those who will pull you up will eventually pull you down again. They may use the valuable time from your life for their work, but when the time comes, they will definitely return you to that past place, those who are godfathers in politics always do politics in a bad way and do not work well for the people.
Because they do not do any good work, they get the results of their own bad deeds in the end, so if you want to do politics, it is definitely necessary to do good politics and besides, you should leave politics. There is no politics like the politics of the past, the current politics is dirty politics.
Keep in mind that in politics there are no permanent friends or enemies, only permanent interests. So it's no surprise that once you're no longer useful to them, they'll try to bring you down or even destroy you, even if they were the ones who helped you rise in the first place.
As for politics today vs back then , imo you've got it wrong. It's still dirty and full of ugly, shady stuff. It's just that tech has come a long way and info spreads like wildfire. So it's way easier for us to see what used to be swept under the rug or never reached the public.
