"I want to pay more taxes" is obviously a stand-in for "tax rates should be higher", not because we love taxes, but because they help us achieve national priorities. Individual action doesn't do that, which is precisely why they're national priorities.
It's all great in theory, but every single developed country wastes billions in taxpayers money every year on all sorts of irrelevant things. Politician pet projects. Projects going massively wrong and overrunning in cost at inflated prices. Inefficiencies. Etc..
I'd rather donate a healthy amount of money to a nonprofit of my choice (and yes, take the tax deduction for doing that -- can donate almost twice as much!). Those charities generally will be able to allocate said resources much more efficiently.
You do realize that people do seemingly contradictory things, right? And sometimes have overtly contradictory beliefs relative to their actions. As Saint Paul referenced; the thorn in his side.
My beliefs versus my actions in this instance is an aspect of the free rider problem. Look it up.
I don't know anyone who is hungry so I can't directly give food to the hungry. One can seek out an organization to provides food for the hungry. I believe that the organization best suited to do this government. Besides, there is more to the proper running of a society than just feeding hungry people.
We need roads, sewers, clean water, a legal system, police, teachers, etc. The umbrella organization that we give money to in order to provide these things is the government.
Empirically speaking, government is one of the least suited and efficient organizations to do this [1].
“[Government] income redistribution agencies are estimated to absorb about two-thirds of each dollar budgeted to them in overhead costs, and in some cases as much as three-quarters of each dollar. Using government data, Robert L. Woodson (1989, p. 63) calculated that, on average, 70 cents of each dollar budgeted for government assistance goes not to the poor, but to the members of the welfare bureaucracy and others serving the poor. Michael Tanner (1996, p. 136 n. 18) cites regional studies supporting this 70/30 split.
“In contrast, administrative and other operating costs in private charities absorb, on average, only one-third or less of each dollar donated, leaving the other two-thirds (or more) to be delivered to recipients. Charity Navigator, www.charitynavigator.org the newest of several private sector organizations that rate charities by various criteria and supply that information to the public on their web sites, found that, as of 2004, 70 percent of charities they rated spent at least 75 percent of their budgets on the programs and services they exist to provide, and 90 percent spent at least 65 percent. The median administrative expense among all charities in their sample was only 10.3 percent.”
Thus it is safe to say that government is much more efficient at accomplishing these goals than charity. Charity is much more efficient at the margins. It’s great for the fringe cases once the majority of the problem has been addressed.
