It makes perfect sense when you realize the people making any of those decisions are, firstly, amoral monstrosities (and no, I don't mind dehumanizing anyone in the top levels of government- they are not humans) and secondly they/their buddies/their family, etc. profit DIRECTLY from the US arms/research industry and the US pharma industry/private medical industry, etc.

Universal healthcare for everyone and abolition of unnecessary insurance companies (a government agency would handle logistics, triage if necessary (oh no death panels!), etc.) would directly result in loss of money for congress and/or people/groups they personally want to see benefit. A truly anti-war stance, no sanctions, no additional arms to ANY country, military drawn and cutting off intelligence agencies completely would also directly cost them money or, at the absolute least, the least corrupt vector, cost them the endorsement of people/corporations that seek to see continuation of arms production and private healthcare.

When you really see the motivations and accept that anyone who lands in those powerful positions always seems to cave to the power or do far too little or simply can't do anything even in those positions (look at Bernie. He's only one man. He says this stuff out loud for like 30 years+ now in congress and what has changed? It's only gotten worse!) you start to arrive at the only solutions being outside the system which perpetuates these outcomes. And now that I have intrigued the assigned lemmygrad FBI agent, I should probably stop there.
