Socialism, since it goes against the very nature of humanity, must always make sure it makes itself look good. Therefore, quantity, rather than quality is counted as the important concern for a company under socialism. Here let me illustrate it for you.
The Socialist Reeses Peanut Butter Cup will have sub-par chocolate (to reduce costs on the company) with a gooey peanut butter (probably not real peanut butter) center that simply falls through the bottom of the Peanut Butter Cup making a big mess of things. Since Reeses has been nationalized under government control there is no competition, so this is the confection you are stuck with. Deal with it, comrade or off to the gulags!
The Capitalist Reeses Peanut Butter Cup is...well.....go to your local convenience store and buy one, eat and relish in the glory of free market capitalism. Since Reeses knows that there is competition out there for Peanut Butter filled confections, they have to make their product at greater quality standards. Ahh there's that keyword: quality.
Apply the examples above to government and you can see why we oppose socialism.
