I guess what I really can't understand about socialism is how so many individuals are conned into giving up even the smallest bit of the power of choice which is due them for some abstract "greater good." Buncha dupes, the lot of ya.
Well, I can say that Canadians have chosen to give up the freedom to choose between corporations that fund our health care for a single payer system in order to see lower costs, better medical results, and a generally healthier citizenry. Our system isn't really all that socialist because the physicians are not employees of the state.
I get to see whatever physician will see me and receive the treatments that she prescribes for me. My taxes are comparable to what I would pay if I lived in California. Our highest federal tax rate is 29% for people making over $129k. The highest tax rate in the US is 35% for >373K, 33% for 171k-372k, and 28% for 88k-171k. That looks to me like you collect more taxes than we do from people who have a medium to large income.
If I take the average Canadian taxpayer, she pays approximately $4500 for health care costs. I understand that the average taxpayer in the US pays approximately $12000 for a comparable insurance policy. So, I get better care, better access, better results, and I won't go bankrupt if my spouse gets cancer. All those Canadians going to the US for treatment? They aren't people who cannot get treatment, or get it in time to save their lives, but those who do not wish to wait for non-life saving treatments. As it turns out, we have a very large medical tourism industry in Canada, seeing as we are cheaper and have generally better results, Americans come here quite a lot for treatment.
Take public works as an another example. The city in which I live owns the electric and natural gas utilities and has for 100 years. The company has always been profitable and returns dividends to the city coffers keeping property taxes low.. The rest of the province has private corporations delivering power. My rates are much much lower than the provincial, federal, and US national averages.
Besides, you give up quite a lot of choice when you submit to the State controlled penalty system we call the criminal law. The benefits of giving up that freedom for the security that comes from a collective is substantial.
The choice to vest control of the means of production fro any sector of the economy is a big deal and should never be done for ideological reasons (nor rejected for ideological reasons). If it can work better, then do it. If it can't, don't. But the proof of concept for certain medical systems and public works is in and they work.
