There is new evidence of the damage caused by unrealistic child support orders. A Washington Post article on Nov 15, 2015 says:
“Of the 2.2 million people incarcerated in the United States, about half are parents, and at least 1 in 5 has a child support obligation. For most, the debt will keep piling up throughout their imprisonment: By law or by practice, child support agencies in much of the country consider incarceration a form of “voluntary impoverishment.” Parents like Harris, the logic goes, have only themselves to blame for not earning a living”
The Post reports that this may change under new rules proposed by President Obama. The new rules would reclassify incarceration as “involuntary impoverishment.” Some Congressional republicans oppose the new rules.
