Being poor is a crime. Not just in the USA but around the world. Not coincidentally, being poor is often a symptom of another crime: not being of the high caste. In the USA (since I don't live in another country and therefore cannot speak to this out of experience or familiarity), "high caste" = White Protestant Wealthy Male (or chattel thereof such as spouse/children).
Being so poor you lack food, shelter, clothing, potable water is illustrated here (circa 2006, taken from a Wikipedia REFERENCE Source):

Whose fault is it that so many are poor?
The GOP would tell you it's their own fault.
The Libertarians would tell you it's nobody's fault. They were born in lousy spots.
The "Christian conservatives" would tell you those people sinned, or their parents did, so they deserve to be poor unless/until they find and acknowledge the correct God, and start treating each other the way that God -- James Dobson's God, the Taliban's God -- requires.

But what does the Bible actually say about the poor?
What does the Quran actually say about the impoverished?
What does the Torah say? (That's what the Old Testament, the punitive text so beloved of the pro-theocratic oligarchy factions, is based on, right?)

In the New Testament, Jesus refers to the commandments in several verses,[19] and condenses them into two general commands:

‘“You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.” This is the greatest and first commandment. And a second is like it: “You shall love your neighbour as yourself.” On these two commandments hang all the law and the prophets.’
—Matthew 22:34-40

Here Jesus is quoting the Old Testament, namely Deuteronomy 6:5 and Leviticus 19:18 respectively.

You want, Religious Right, to claim this is a Christian nation?
You want to say that we have an obligation to follow God's law first, Religious Right?
Then follow the law as God's own Son laid it down:
the law as God's own Son laid it down

Matthew 25:35
For I was an hungred, and ye gave me meat: I was thirsty, and ye gave me drink: I was a stranger, and ye took me in: 36 Naked, and ye clothed me: I was sick, and ye visited me: I was in prison, and ye came unto me. 37 Then shall the righteous answer him, saying, Lord, when saw we thee an hungred, and fed thee? or thirsty, and gave thee drink? 38 When saw we thee a stranger, and took thee in? or naked, and clothed thee? 39 Or when saw we thee sick, or in prison, and came unto thee? 40 And the King shall answer and say unto them, Verily I say unto you, Inasmuch as ye have done it unto one of the least of these my brethren, ye have done it unto me.

The treatment of widows, orphans, the homeless -- if you want anybody to believe your claims, why don't you live as though you believe them?

Because you don't. You use them as a justification for tyranny against the less fortunate. You refuse the words and the advice and the demands of the Christ you claim to follow -- moreover, you demand that in order to fulfill the tenets of your version of Christianity others do the same.
