Agree mostly but I don't think unions are the solution to over-consumption. They're good for income inequality worker safety and a bunch of other things, but they're just as incentivized to increase consumption as corporations. Consumption is good for workers since it guarantees job security and possible increases to wages. To counteract these interests you need something representing the interests of everyone that will be negatively effected by over-consumption and the climate change it causes, such as a truly representative democratic state.

Syndicalism is great for organizing a community and handling it's problems but it can't handle large scale problems that require self sacrifice like war and climate change, for that you need larger organizations.
