There are many ways people can exert power over others.
True, but the state is most effective.
One of the major selling points of Democracy has always been the idea that government power will be shared by all people. The problem is that government decisions and therefor government power is sold to the highest bidder.
Democracy is three wolves and a sheep voting on what to have for lunch.
Democracy crushes the rights of minorities on the vote of majority - it is mob rule. A republican form of government, such as we have, codifies protections of minority rights.
It seems hard to believe that so many people are so easily deceived to think that losing power is actually good for them and then blame those with the least amount of power for all of the problems.
Right now the Chinese government exerts an incredible amount of power in our labor markets. Right now corporations exert an incredible amount of power in markets and in government. To do nothing is to let others rule over you. The end goal of socialism is a better form of democracy and a better economy for all. It turns out that inequality of income and of power is actually really bad for everyone in the long run.
To give government even more power - to sell to the highest bidder - is suicidal. Socialism requires authoritarianism. Sane people do not work for the detriment of themselves and their families without force. This is one of the reasons for the war the left wages on the family - it is an impediment to the goal of enslaving all to the state, i.e. Socialism.
Reduce the size and scope of government, and the ability to sell us out will be removed from them. Socialism cannot exist in a free society. Where people are free, they will trade among themselves. Drive on any Saturday morning in America and you will see yard sales all around. When people are not under threat, they trade. Even in prison, people trade.
Trade is the peaceful manner in with people deal with one another. Socialism is the opposite of trade and MUST, by nature, employ violence or the threat of violence to coerce people to comply. Socialism is against the nature of people. People by nature want to coexist peacefully with others, which means the trades of goods. Socialism is the quest for power over others, taking from the most productive and using the ill-gotten gain to buy the loyalty of the dregs of society, which act as muscle for the Socialist thugs.
