The "wealth" of a nation is largely dependent upon how efficiently it can produce (or obtain via trade) the food, shelter, and clothing required and desired by its citizenry — transportation, communication and energy being necessary auxilliaries of that production.
Although private sector jobs, by necessity, provide those goods or services needed and desired by the consuming public (such production representing our nation's wealth) government expenditures consume that wealth — sometimes wisely, but often foolishly.
Herein lies the basic error underlying Socialist theory: As governments extend their wealth-consuming tentacles further and further into the private sector (indulging in unending attempts to legislate goodness) — freedom and prosperity fall victim to that process.
Socialism is like salt: a dash here and there is good, but a cupful ruins the product.
