I'm curious about the income portion of it mainly because it is the reality I live in, regardless of other advantages. I'm well aware there are some limitations to the choices I've made in life, like any other set of choices. However, if I care purely about the financial benefits...without a study showing one way or the other how can anyone make an informed decision based on facts rather than anecdotal evidence? :/ That is the part I was trying to get at.
