one side is way worse, especially with human rights and human decency related topcis, but you're right, it's mostly just politicians. the people who'd be great at it are usually like "fuck that". the shitty people that see an opportunity to use it to get rich are the ones that often end up in politics, unfortunately. and that's shitty about the rail thing, that's actually a thing russia has done many times. the metro station in chelyabinsk is a big example of this. millions of tax money going into it, decades later, still nothing, every so often, when the corrupt want more money, they bring the topic back up, make a big splash in the media about it, get more tax money, rinse and repeat
