to maximise his own profits and personal wealth
Not entirely true.
Dyson applied to expand the current premises at Malmsbury, but was turned down. That's largely the reason why production at Malmsbury ceased and the site now focuses on R&D, promotions, HR, finance, procurement and distribution. Although I imagine cost cutting was an added bonus.
Keith, what do you mean about "electrical safety and fake products"? Just because something is made over-seas, doesn't make it unsafe. Anything sold in the UK has to pass regulations, regardless of it's country of origin.
I believe Hoover/Candy still have a manufacturing plant in Portugal, also.
Sadly, cost-cutting is not limited. Everyone is doing it. Even Numatic, the only remaining British manufacturer of vacuums, have cut the quality of their machines to save on costs - the current range (although good) are not a patch on the quality of the older machines. Miele have had to put their prices up to keep quality high. This is especially noticeable in their washing machines, which have rocketed in price over the last 5 years to keep quality high.
