Scrump - you've actually hit the nail squarely on the head.

Scientists can only do research when they have money.

The people who give scientists money for research generally have one or both of two ulterior motives -

... can you guess what those are? ... right! ... more money and military power!

Most civil technology is based on civilian applications of military technology.

And most civil technology is designed for profit.

Most civil technology is designed to last for a finite time after which it must be replaced - it's true - they don't make 'em like they used to and that was when they built 'em to last.

This is to ensure the fluid continuity and growth of the consumer economy. (people don't need to buy washing machines if they already have them, until they become unserviceable)

Back to the point,

Scientists are not the objective open minded free thinkers that they once were.

Their need to put bread on the table requires them to do specific research for specific purposes - those of the company they work for.
