The system of checks and balances were never made for what we have today because there was no frame of reference for what life would be like. Not saying there shouldn’t be any, just that they aren’t working anymore as they should. There is no guarantee that scientists are enlightened but they have a lot more tools at their disposal than the average bean. And not only that, most if not all, politicians are lawyers who have worked for corporations, or corporation owners themselves. They only care about themselves and they have the system rigged to support them and it’s been this way for years.
