Are self funded PhD's worse than I think?
Obviously it's a huge amount of money invested in something that may not work, but is it akin to 'vanity publishing' where they'll accept any old candidate because they are free labor, and skimp on supervision because it's not costing the collage anything?
EDIT: I'm not knocking the quality of a successful self funded PhD as it would have to go through the normal external examination etc, I'm more questioning if the chances of said success are lower because they are not being selected as best (and most likely to succeed) candidate, but as best person willing to work for free.
