It's the biggest bakery in the UK and most successful, so it's down to their success that they can re-invest in top talent. 5000 staff will not market or advertise the loaves as well as Samuel L Jackson can, which means when he (or DeNiro, Clooney, Stallone or Kay) all advertise the bread, their talent sell more than any internal staff member could, meaning higher profits and more Xmas bonuses for the staff. Speculate to accumulate is what they call it.
A quick cautionary word for everyone based upon the above comment. If you have absolutely zero knowledge whatsoever of basic economics you'll spend your entire life pissed off at literally everything, like this chap who is fizzing over a comical advert for bread.
