How to Make Policy Arguments to Policy People

i think one of the great enemies of change is the a inevitablism of capitalist realism and the idea that there is no alternative. So if you cand make people believe in an alternative, then they might work for one. If people don't believe there is any alternative possible, they won't work. For one why? Why would you? And so all that together, i think, i is part of how you mobilize people to care about stuff. Yes?
