Agreed, but SP101 is just a lowly troll. My guess is that they are't even concerned with grad school, hates what they do, or couldn't gain admission for obvious reasons (What PI in their right mind would take someone like them?). Nonetheless, we will continue to vote down everything they say because it is funny to watch them flail about like a beached whale. Although, "washed up" doesn't even begin to describe their current disposition.
Personally I applied for PhD programs because, well, I could.
I'm one of those weirdos that has a job in industry but is giving it up for more education. However, I see it as an opportunity to gain more independence in my research as well. I could continue to work my way up the corporate ladder, but at this rate, it seems the PhD may actually shorten the amount of time I spend on the fringes of publishing my own work. It also helps that I'm guaranteed funding for full tuition and a sizable living stipend no matter where I choose to go.
In the end though, I guess I could care less about money. I grew up reasonably poor, and to be honest, it wasn't that bad. In a lot of ways it was kind of fun. Should I end up jobless, alone, and eventually homeless, so be it. At least I tried to follow my dreams. That in itself is very satisfying. Whether you're STEM or humanities, following a dream should be reason enough to pursue a graduate degree, fiat currencies be damned. Luckily, rock bottom in the United States, for most people, is still relatively soft.
