My conclusion is based on one assumption: The source of financial problems is either bad money management or lack of enough earning capacity. Giving away free money fixes neither in the long term (this is another assumption.)
If their problem is bad money management, giving them more money and hoping that they'll fix their money management habits sounds like a very ineffective approach to fixing the problem.
If their problem is lack of earning capability, that needs to be addressed through education and job creation. Giving a single mother with 2-3 kids an extra $1500 per month might make her life a lot easier but it won't allow her to begin earning an extra $1500 on her own unless she uses the extra money to make very smart choices. Given the real world demands that she would be under, it seems that probability is not likely in her favor and again seems like an ineffectively approach to solving the problem.
The article really boiled down to: give people free money and they'll make wise decisions to help themselves. It didn't provide enough arguments to support that thesis and from just my understanding of human nature, I can't see this being an effective approach to solving the problem of poverty.
