The treatment of wealth and poverty in the New Testament fail to rule out all conservative positions as unChristian, but some versions of it strike me as unacceptable. For example, the ethics of Ayn Rand and the ethics of Christ simply can't be reconciled. Greed is not good.
You can't, as a Christian, say that the wealthy are wealthy because they deserve to be, or that a system that helps the rich get rich and allows the poor to get poorer is acceptable. Eric Cantor, for example said that he thought his role was to help the people on top stay there. That has to be un-Christian.
You can make the argument that helping the poor is perfectly good, but using the coercive powers of government to do so is to do it in the worst way. But it does seem that if you accept the laissez-faire argument, you can't turn around and back out of use the government to help your favorite industry. You can't oppose welfare and the support corporate welfare. I don't even know what disentangling the government from the economy would even look like. IF the government is going to help someone, it has to be the people on the bottom.
What I especially dislike is the kind of cafeteria conservativism that appeals to conservative principle so long as they serve the purposes of the big businesses that fund Republican campaigns. But that is what usually happens when you elect conservative candidates.
Watching the Republican debate last night, the argument seems to be that they kept arguing that markets have a regulating effect on economics, and on that account is should be preferred to government regulation. So, if businesses are profitable, they will create jobs. But, corporations are not national entities, they are international entities. And while workers' rights are guaranteed in America, they are not guaranteed in the Third World. At present, businesses have no incentive to create jobs in America. In fact the tax code actually supports outsourcing. So, as far as I can see, just letting capitalism run its course will NOT create jobs in America. Quite the reverse.
