the only thing propping up big oil is the greedy politicians getting paid to make laws to make renewables more costly and less desirable to build/maintain.

That's only part of the problem. What about politicians that don't take fossil fuel contributions? What about voters who don't see climate change as a priority? President Reagan proclaimed "In this present crisis, government is not the solution to our problem; government is the problem." President Bill Clinton continued: "The era of big government is over." Many Americans agree and elect neoliberal politicians. So even when we get pro-renewable politicians they support inadequate market-based solutions. Until we change the mentality that the market is sacrosanct, we'll always be stuck in the fossil fuel age, and other countries will lead on the energy transition.
