1. I'm showing that government intervention is the only way lower classes have ever gotten any rights or benefits.
2. you talk about government as if all governments, everywhere, in all parts of history, are the same organization. Government was not responsible for the genocide of the Native Americans, or the Jews, or Soviet dissenters, or elder citizens in Maoist China, or any other act of mass murder. Government is merely a tool, used by whoever controls it for their own purposes; White Protestant Americans wanted the Native Americans off of the land. Adolf Hitler and the Nazi party wanted the Jews dead. Joseph Stalin wanted dissenters Dead. And so, with their control of government, they tried to accomplish what they wanted to do.
On the other side of that argument, there are people like Abraham Lincoln, who used government to free the slaves and attempted to heal the nation after a bloody civil war; FDR, who used the government to intervene in the economy during the depression, putting people back to work and massively improving the country's infrastructure; the government of Iceland, in 2009, which got its economy back on track after the recession hit by listening to the will of its citizens and punishing those responsible for the crash, rather than bailing them out. Government power goes not have to be limited, it only has to be controlled by the right people, meaning putting power fully in the hands of it's citizens.
