Hence science tends to flounder around for decades at a time - or centuries as it was in the past - and suddenly lurch forward when some virtual unknown, and Einstein is a perfect example, steps forward with proof that some of the fringe ideas established thinkers were afraid to explore actually have merit.
Then there is this period of tremendous progress until the potential of whatever idea it was that started the revolution is exhausted, and then it becomes dogma that must one day be rejected by a better theory and so on.
Scientists like to keep their jobs. Also they are generally paid to do rather specific research - financed by the government (military) or corporate interests. So it's not that science is directly biased by its financial basis to any great extent (to a certain degree sure,) but the types of questions being seriously investigated are limited to what there is funding for.
