Many people in fact don’t know what they believe.
For instance, there are people who say that they believe that government should be run like a business.
They say it but they don’t believe it.
Consider a single person and a family of four (consisting a mother, a father, and two young children) in which there is only one wage-earner.
If the single person and the family go to a restaurant, and if the single person and the wage-earner order the same things, the single person will pay less than the family will pay.
However, if the single person and the wage-earner make the same income, the former will pay more in taxes than the latter. If the tax is flat, the former will pay more per capita than the latter.
If the government were run like a business, not even a flat tax would be available. If the government were run like a business, the family would have to pay more in taxes than the single person.
Unless you believe that the family should pay more, you do not believe that the government should be run like a business.
Of course, most people think that the family should pay less. If so, you are fine, in principle, with transfers from the better off to the worse off. If so, you are fine, in principle, with being taxed at a higher rate to help others in society. The question for you is not whether there should be transfers but to whom the transfers should be made.
Of course, now that the implications have been pointed out, people who have said that government should be run like a business will say that they meant it should be run like a business in terms of efficiency, say. To which I reply, then you should have added your qualifiers sooner.
