This is a common thing happens in different countries where the government mandatory give assistance to there citizens with disability, and the sad truth is that the assistance from government is not enough.

First, that will only work if they are only physically disabled but they can still use their own hands because they are mentally challenged, the bad news is that they still need to rely to their family and the government. And another one is if they chose to trade, they still need funds just like a regular trader and it's very risky for them.
