The assumption that only good comes from the federal government spending more on poverty programs is patently false. These programs have probably harmed more than they have helped by giving money to people without any accountability. It destroys human dignity. The federal government needs to get out of this arena and return it to the community where it belongs.
It would be helpful if the signatories would show, next to their names, the amount of money received from the government by the organizations they are affiliated with. For example World Relief, according to the latest Form 990 available on Guidestar, received $31,0307,682, OVER 60% of their total, in contributions from government grants. That's right World Vision receives more money from the government than it does from Christians. There is some self-interest in advocating for more government spending.
For just one other example - Catholic Charities (just the main organization, not the individual diocese) receives $73,079,999, 85% of their donations, from government grants.
Just two of the organizations listed on the list of signatories receive over $100 MILLION from the government. Their idea of compassion is the government taking money out of my pocket and yours and giving it them. How noble. How compassionate. But the idea of advocating for one's own interest in the name of the poor has a long history - John 12:6.

Just one more - World Vision received $198,653,528 in government grants. This is only about 19% of their contributions but still a very substantial sum of money. The officers, directors and trustees split $2.7million among themselves personally with $429,579 going to Richard Stearns
This means only 3 organization on the list receive over $400 MILLION of government funds.

Greg, so you are saying that money distributed by these organizations harms human dignity and is done without accountability? I assume that they distribute government money just like the donated money so this must be the case.

There were a couple of points that I was making. The first is that government benefits to the poor are often a source of harm to the poor as a group (certainly there will be some who are better for the help). The automatic assumption of the signers of the letter is that THE Christian thing to do is to encourage more government spending. I contest that assumption.
A second point that I was making was that these signatories themselves benefit from this government largess. They are self-interested parties in the discussion.
As to whether their own programs are destructive, I can't say with any certainty. If the fact that they receive government funds means that they are restricted from imposing accountability on the beneficiaries, then I can't imagine how they could not being doing harm.
If you wanted to read further on the destructive effect of misguided Christian efforts, I would point you to Toxic Charity by Robert Lupton http://www.christianbook.com/toxic-charity-churches-charities-those-help/robert-lupton/9780062076212/pd/076212?en=google-pla&kw=academic-0-20&p=1167941&gclid=CKflka-t3LUCFckx4AodgCYAIw.

A tooth (plural teeth) is a undersized, calcified, whitish form initiate in the jaws (or mouths) of innumerable vertebrates and occupied to break down food. Some animals, surprisingly carnivores, also use teeth for the purpose hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but fairly of multiple tissues of varying density and hardness.

The unrestricted structure of teeth is similar across the vertebrates, although there is considerable modifying in their fabric and position. The teeth of mammals have profound roots, and this decoration is also initiate in some fish, and in crocodilians. In most teleost fish, how, the teeth are attached to the outer rise of the bone, while in lizards they are fixed devoted to to the inner side of the jaw by way of harmonious side. In cartilaginous fish, such as sharks, the teeth are attached by perplexing ligaments to the hoops of cartilage that construct the jaw.
