It’s not immediately obvious why you need scientists in banking and offices. But everything, from methods of communication (like phones and communication) to producing bank-notes that are difficult to counterfeit, depends on advances in science. Scientists developed the new plastic notes to make it as difficult as possible to copy them and to increase their water and tear resistance.
Banks, accountancy firms and insurers look to employ those with science qualifications because they have good mathematical skills. Those companies that invest in many projects to make profits need scientists to decide what new scientific ideas will be successful and make profits.
