The amount of resources available to spend on research is finite. Distribution of limited resources is politics.
Historically, scientists either were well-off and independent (e.g. Ulug beg, Newton, Cavendish), or worked at the expense of very rich personal patrons (e.g. Tycho). This limited the number of potential scientists, and the amount of science done, quite drastically.
In 18th-20th centuries it was somehow overcome, when partly states, partly industries gave more scientists more resources. By mid-20th century, the system started to develop cracks, as science became increasingly driven by formal metrics, such as impactful publications. The metrics are actively gamed, but worse, since science is unpredictable, honestly checking everything and building a picture of reality became a worse strategy than going for a flashy if more weakly researched result.

I don't know a good way out of the current trap.
