Healthcare ??????????????????

why r cons so down on "socialized" healthcare when we have "socialized" firemen, "socialized" police and "socialized" schools. what i mean is that why should we not have government-run heathcare when all those things i just mentioned are government run. insurence companies want to make a profit and not help you. in england and france they have great government run healthcare so why can't we. like insurence companies find ways to not help you. If your house was on fire would the fire dept. not put out your fire because the fire was caused by a prexisting condition on your house??? no they would put out the fire. why cant healthcare be that way???
