A massive and alarming list indeed . . and not finished yet.
Regarding clothing (fashion) I think the impact of 'value' shops like Primark have had a massive influence. The large supermarket chains also do an increasing range of clothing - not top quality stuff, but who cares when you can buy a suit for £50 and throw it away after a few months.
Casual wear, shoes, jeans, tops etc are now cheap as chips (which is a silly saying considering the price of a bag of sliced fried potato), and it's the price general consumers are looking at instead of quality.
With electronics, anything you buy today is probably superseded by a 'fantastic upgraded bells & whistles must have' version by next week, buy it online now for £££££ cheaper than instore
Personally I think we import far too much dross from abroad, in all areas not just clothing, but while people are willing to buy it nothing will change.
