Hair braids etc could be done by a family member or a friend for free (wanting to pratcise).

I think sometimes it's really hard to make judgements about people unless you know them very well. I mean some problems you won't even see- like mental illness for example. Or cannot work because of seizures or being partially sighted (not all blind people walk around with non-foccusing eyes and sunglasses).

Yes everyone in the work has a touch of greed in them and will know how to "work" the system. The rich do it, the poor do it and sometimes even the middle class. Who doesn't want something for nothing? I don't think any system can be perfect- look at communism- it had all the good intentions in the world (spread the wealth, don't have wealthy elite) and that didn't work. I think everything is a compromise and we can only hope that people don't slip through the crcks. But of course they do.
