by definition socialism is handing more power to the government. technically sanders doesn't advocate for a true socialist state, just for certain government programs that would be socialist. also bear in mind socialism isn't inherently bad. if socialism in "any form" always goes overboard then we should already be waiting for public schools and roads to come back and bite us
the question is if you trust the government to have that power as a solution to a problem, and that's just a matter of your personal values
