That was certainly part of it. The structure of neuro academia meant that I would be stuck in a postdoc position for 3-10 years paying, likely, around the NIH minimum of around $55k. Which goes along with more responsibility and drastically less job security than a graduate student without any better chances of actually getting a faculty position.
Combine that with the fact that I didn't have the drive or disposition that the field selects for and I was out of there immediately after I got my degree for a more lucrative, more interesting (to me) job with a better work-life balance.
