That’s good! No seriously, PLEASE start writing a long party manifesto with points you research thoroughly. Start with the topic most dear to you. Then look up why this has not been done yet, if there were previous attempts, why they failed, how they could succeed. Try to think about all other aspects of life a policy you would enact would touch.
For example, could investing more into railways cause a decline in car sales and subsequent loss of jobs? Could you maybe license high-speed rail technology from Japan or China, in exchange for easing of microchip sanctions on them? Things like that.
Do that, and over time you will be a fully aware and engaged citizen, deserving of the title. Even if your new party doesn’t work out, you would end up with way more knowledge about good governance than even many in Congress today. No need to scream into the void, people with their heart in the right spot like you are in the majority, not minority. You’re not alone.
Also check out your state third parties and see if there is already a party that comes close to what you want for the country. Almost every state has them in some form, but most people don’t even know they exist. The Forward Party comes to mind. There’s also the “Liberal Party USA”, though they are in dire straits.
Don’t think that’s “capitalist propaganda” as we just found out what the rich will do when faced with higher taxation. They take over the country. In the absence of that possibility, they would absolutely put their HQ somewhere else. No one sets up shop in Ireland because they think the weather is nicer there.
