What is the point of government?

I had another conversation with my conservative friend today. He was saying that "class warfare" isn't the answer to our economic problems. Which is apparently his opinion on asking the people with all the money to quit hogging all the money.  I don't mind if people have more money than I do. I don't mind if people have a whole ton of money and I don't.  But I do mind that 1% of the people have ALL the money.  So I have been thinking today, if the government isn't here to provide the services that We The People need, then what is that point of it?  So I Googled. And I got this answer from Yahoo Answers (which wasn't even chosen as the best answer, but I think it should have been).

For the United States, the Constitution gives certain goals for the government in the preamble:

To form a more perfect union - Make it so the people of different states can conduct business, make contracts, have compatible laws.

Establish Justice - Criminals get punished. No running between states to avoid prosecution.

insure Domestic Tranquility - Enact such laws that allow people to live peacefully with each other. Provide institutions that enforce laws (Police, Courts, etc)

Provide for a Common Defense - Establish diplomatic capabilities for the whole of the union, establishment of a military.

Promote the General Welfare - See to the needs of the people. This includes making health care available to enabling charitable causes.

secure the Blessings of Liberty to ourselves and our Posterity - The government is intended to provide freedom. In essence, this is a 'do no evil' kind of statement. (Posterity - Those who come after us... eg. Children, Grandchildren, etc)

They're right. That is the point of (the US) government. I don't see "provide tax breaks to the wealthy" or "corporations play for free" in there anywhere. Hell, I don't even see "protect unregulated capitalism." Unregulated capitalism is evil, greedy, and wrong. But I suppose when you support a fascist theocracy, evil, greedy and wrong are small potatoes.

Damn, I'm on a roll.

I've been thinking a lot lately about Republican and Libertarian political stances. Most of these people, AFAICT, call themselves Christians. OK. But what I'm wondering is, if they're Christians, then why do their beliefs sound more like LaVeyan Satanism than like the things Jesus supposedly said?

Example: Christianity teaches that it is easier for a camel to go through the eye of a needle than for a rich man to get into heaven. I think none of them read that page. Another thing they don't appear to have read is when Jesus tell his people that they need to give all their stuff to the poor if they want to follow him.

OTOH, "LaVey felt that intelligent and strong people spent too much time caring for psychic vampires — weak individuals who always demanded attention and care, yet would never give any back. He taught that Satanists should strive to remove themselves as much as possible from such people in order to live in accordance to their instincts and individual wills." (This is from wikipedia.) This sounds a lot more like dog eat dog Republicans to me.
