When the Koch brothers can turn on a firehose of money and turn states back in time into right to work states, then we need to drain that giant ball of wealth. You are correct, we do still have some non-corporate mechanisms in the government, and I'm totally against making anyone feel helpless and that there is no way forward.
We've been in the circle the wagons mode in the labor movement, and that needs to change too. We need more tactics to make anti-corporate allies in areas that have not always been served by industrial unionism but suffer greatly from the ravages of capitalism.
I think those are things that need to happen and are starting to happen. But we need capitalism to feel way way more grassroots fight and pain from battle before we talk about sharing the sand toys. The US has the distinction of being the government where many of these corporations have their home base. In other countries that have more socialism they don't have that power base and have to be a little less assholish. We don't get that consideration closer to home.
Let's look at Mexico, much closer to home here. They had workers rights written right into their constitution, now gone under direct attack, almost a stroke of the pen, by an election that was won by a corporate backed power. I'm sure there are powerful American corporations that have their lunch-hooks in that too. We need to get processes like that stopped, so we have more room to work forward, rather than always being in crash-paddle mode with our democracies.
