As a piece of entertainment, I enjoy "Dragon's Den". Having watched it this evening, it occurred to me that virtually all the entrepreneurs in this episode, and previous ones, are inventing products that are really not needed. There was someone with an automatically filling bath, a gadget for scooping up dog mess from gardens, and a package holiday company aimed at the younger festival-going holidaymaker. The only product that seemed of any real use to me was the one that restored mobile phones that had been dropped in water. I suppose it could be argued that mobile phones aren't a necessity, but at least such a product avoids a phone being discarded and the subsequent waste of resources.
It got me thinking that we have lost sight of what is really needed in the world, and sophisticated marketing has encouraged people to feel permanently dissastisfied and to buy things that aren't really necessary - continually upgrading their mobile phones, TVs, computers, etc. etc.
I'm sure some people will say - well, we could probably do without washing machines, tumble dryers, dishwashers, microwaves, etc., etc. but life would be so much more tedious without them. I can see that, but is it really necessary for mobile phones to become more and more sophisticated, for TVs to provide higher and higher definition, etc.?
Surely what all people in the world really need is good housing, good food, good healthcare and good education? But a substantial amount of the world's resources - both labour and materials - seem to be diverted into areas that aren't so vital.

, or that will make life easier etc. 
. I want it and carry it home e.g. in the shape of stones or bits of driftwood. Husband buys paintings, I can look at them and not want them.
