The duty of the people to support the church has been established for several thousand years. Also, the duty of the people to help support the widow, orphan, and 'stranger'.
The Old Testament, for one, spells this out and calls for a 10% tithe to the church. Similar payments were made to the state although I don't think a specific amount was spelled out.
The state may become immoral if it takes too much. It fails in its responsibility if it does not have good reason for giving away money. That said, our government does have responsibilities which must be funded such as providing for the common defense. I agree that both Dems and Reps are all too willing to take more money, and all too willing to spend it in wasteful ways. To their credit, Reps want to reduce the amount of money taken. It is not clear to me that the Dems want to reduce spending. They want, instead, to redirect it from defense to social needs and desires. That has been proven to be a disaster. Unfortunately, neither party wants to really throttle back the size and scope of government, so we wind up arguing about the fringes of the problem.
According to Marxist doctrine, socialism is a stage of society between capitalism and communism where private ownership and control over property are eliminated. The essence of socialism is the attenuation and ultimate abolition of private property rights. Attacks on private property include, but are not limited to, confiscating the rightful property of one person and giving it to another to whom it doesn't belong. When this is done privately, we call it theft. When it's done collectively, we use euphemisms: income transfers or redistribution.
It's not just left-wingers and Democrats who call for and admire socialism but right-wingers and Republicans as well.
Republicans and right-wingers support taking the earnings of one American and giving them to farmers, banks, airlines and other failing businesses. Democrats and left-wingers support taking the earnings of one American and giving them to poor people, cities and artists. Both agree on taking one American's earnings to give to another; they simply differ on the recipients. This kind of congressional activity constitutes at least two-thirds of the federal budget.
Regardless of the purpose, such behavior is immoral. It's a reduced form of slavery. After all, what is the essence of slavery? It's the forceful use of one person to serve the purposes of another person. When Congress, through the tax code, takes the earnings of one person and turns around to give it to another person in the forms of prescription drugs, Social Security, food stamps, farm subsidies or airline bailouts, it is forcibly using one person to serve the purposes of another.
