A few voices on the internet don't have any leverage vs a whole silence country.
It's all I can do right now, other than write my Congressman.
Don't hold your breath. I don't think it's an age thing. I felt like you do when I was in high-school, and/or in college... now "my generation" is well into the range where people my are are serving in Congress and other government positions, and it's still business as usual.
There just seem to be certain types of people, regardless of age, who are drawn to becoming part of the State and who are good at getting elected. And every generation churns out its measure of assholes.
In the more stable US two-party system, you may need to resort to somewhat older methods, which are still widely used around the world even in present days:

Meanwhile, Americans think the President is some kind of God-king. The powers a President has are granted by Congress, the money is voted by Congress. The President has enormous day to day influence and power, and could at an order destroy billions of lives. Yet the President has no guarantee of a workable Congress and Congress has no incentive to work with a President.
The only thing that can cause the Washington system to act collectively is some terrifying outside threat, and all they will ever agree on is the kind of madness that's led us to this pass.
So, actually? The Westminster system is pretty damn good, constitution or not. Americans think they're badasses for having a revolution. One. And a civil war. One.
Britain's constitutional system is more thoroughly underpinned by blood and terror and war and suffering than the USA's. By a long shot.
