Meh, would it not depend more on the saturation of the field? Like a physicist may literally only need a computer and desk (and a small salary, supported by teaching), while a biologist might need lets say contracting funds to do DNA sequencing, and yet even in that scenario the latter might still find a job more readily than the former? Though heavily influenced by factors such as willingness to move to elsewhere especially another country.
Additionally which (sub-)field someone is in has implications for how readily available even small amounts of funds are, especially if the various committees are using the hiree to obtain funds from a known source?
