well, we do get a vote in leadership that is there to manage our interests. Back after the mortgage meltdown, everyone generally took it up the butt. Our pensions basically got frozen for a good 8 years after the Fannie and Freddie debacle. I'm not sure where all the stats are being pulled from by the other dude but yes, generally a large fund will put their investments in firms that are backed by public spending. The defense companies are a no brainer so it's not like we are supporting them building weapons, they just have high demand.
If the world suddenly goes into the trash can tomorrow, who can you rely on? Damn right if you choose companies who are getting their ends from the defense sector. Private, for profit, prison systems have long been a safe bet for the same reasons as well. It doesn't matter to the bean counters because they don't give a flop for the company ethics or mission statements, they just wan't to see that bottom line growing year in and out.
How we are able to spin pension funds into some sort of global war mongering cabal is a real stretch to me but sometimes we just need to consider the source and work from there.
I do read my prospectus in all my funds I give my money to including my pensions, and I have to be honest, as long as the number is green, I smile. If I tried to micromanage the hundreds upon hundreds of stocks they own I'd go broke before I pulled a lever.
It's an old trope used for ages that the corporate world is killing us. Some people need to realize that capitalism is what built this nation. Does it get out of hand at times? Yes, but we need to take it for what it's worth. It's engrained in our DNA.
