That's true what you say about market capitalism but market capitalism only works for the public good when it is well regulated so that markets are not abused, cheated, manipulated, monopolized, etc.
This is where you jump the tracks of sanity and board the Crazy Train. Point of order: We have no 'system' which ensures corruption can not happen. You are assuming that this entity called "government" will forever be impartial and honest, and non-corrupt, and this is a fantasy notion. Free market capitalism works for the public good because it provides services according to demand, and allows for competitive pricing and competition in general. When you allow government to 'tinker' with it, you sometimes have very adverse consequences, like the recent housing/financial collapse.
When you've done away with the capitalist system entirely, and you lay it on government to handle, the results are the Post Office... the Tag Office... or worse, Solyndra and 'bailouts' (aka: payoffs to political donors) out the wazoo. We still very much have the same problem, we just don't have a 1-800-Customer Service line to call and complain anymore. We can't go look in the Yellow Pages for better competition, that option has gone bye-bye now, we depend on Government.
Having said that, there is a time and a place for socialism. Socialism is legitimate when free markets are not able to provide the goods and/or services that are needed for the public good. Would you want our military to be based on free market enterprize and lassiez-faire capitalims? Fuck no.
But THIS isn't Socialism. It is 'socialist' in nature, and I know that is very confusing, but it's important. Our Constitutional Federal Democratic Republic, is charged with the first and foremost power to assemble a military for our national defense. As far as our national government's legitimacy goes, that is pretty much the main thing it is there for. And yes, the concept that we all pay a little bit to fund this military, is a 'socialist' principle, because we share this burden as a society.... but that does not make it Socialist.
Would you want to have a completely free market educational system? Hell no, only a fraction of our people would get educated.
Is there a marginally higher rate of educational success under the Government system? It seems to me, the current system is making our children dumber and dumber, because they continue to lag behind the rest of the civilized world. This is a really good example of why a Government-only system (single payer) is BAD! Meanwhile, when people are given the flexibility of vouchers, and are able to create charter schools and explore home school options, students are flourishing, grades are up, more are entering college and furthering their education, fewer are 'dropping out' and this competitive system seems to work very well. So... I want to try something NEW.... Progressive, if you will?
Would you want a completely free market health care system? No way, our publicly owned hospitals and clinics that comprise 75% of our nations health care system would collapse and our health care system with it except for the very wealthy.
But wait, up until a couple years ago (idk, some liberals claim not until 2014), we had a completely free market health care system, and it didn't seem to be drying up or blowing away, and I don't see dead corpses littering the streets from all those who lacked medical care because they were too poor. Oh wait, we passed indigent care laws in every state and we have Medicaid now, I forgot!
Is it good that the market competes or compliments these socialized instutions in our nation? Damned straight it is! So there is a time and a place for socialism, within limits, to meet the publics needs when the free market system fails to do so. Our current health care reform debate is an excellent example of that. We wouldn't even be having that debate if the free market wasn't failing us so badly in our national health care system.
It is a debate we are having because the Democrat Party, in their zeal of power, decided to ram through legislation without any bipartisan support, most of which, they didn't even bother to read. The effects are being realized in a complete stagnation of new jobs and economic growth, and after blowing through nearly $3 trillion in borrowed money, we are no closer to recovery.
