Live in that world as a struggling student scientist, juggling the prospects of a "marketable" thesis versus an ethical one, as debts pile up and staring down the barrel of your entire life amounting to being yet another mediocre drone / living on the streets / not being a scientist at all.
The prospect of being completely broke, unable to afford rent, unable to afford food, being an embarrassment to friends and family, these factors exist and must surely inform the judgement and behaviours of students in a position to have a study funded.
I know of phd's still struggling in their careers against the same thing, where an institute is more interested in publicity than the actual science.
The symptom may be half-assed and meaningless experiments but that is not to say the individuals responsible aren't capable or willing of so much more if the appropriate supporting social structures existed to allow ethical scientific thinkers to exist, or if institutions stopped taking in students for the money and instead tested applicants for profit.
It's easy to point out the problem but how can it be solved? To me, I think there needs to be publicly funded institutes that have no profit motive and exist purely to intake the best academic minds, this might seem anti capitalist but as a model it is an investment in the future of a society that is calculated in quality rather than quantity.
