That depends on how you see gradual reform we need to build split power(power lose from the goverment such as local farming arming the working class) and change cultural stuff in that way gradual reform is needed for a revolution to start but if you mean it in the voting way its not gonna change much the whole voting system everywhere is to wraped up in big capital to bring actual changes best we can do is fight off collapse by voting left On revolutionary action and if it would work i think it would the system is not too stable right now everything is slowly crashing down it just needs a lil push(not saying it would be easy at all)
