I guess, for a govt to exist, it has to collect taxes somewhere. Options would include:
Collection on Income
Collection on Sales
Collection as part of a Census (yearly, flat rate everyone is enforced on)
A census tax would cost too much time and money, so that leaves income or sales. From there, I would prefer a sales tax over income. But, if we are already paying income, we shouldnt be paying sales as well.
A flat tax on personal income is the ideal way to go, but only for those items of government that are truly general welfare.
For the rest, user fees.
Texas has sales tax, but no State income tax. And property taxes are local (mostly for schools).
