Its the global economy. If you want to buy a good quality, hand made garden set from a company in Bradford then you can still do that. Its just that most people would rather buy something cheap from B&Q with the expectation that they'll be back buying another set in a couple of years when the old one has fallen apart. People don't really buy things to last anymore, they buy things for convenience.
Another example would be clothes shops like H&M, Primark and New Look. People know they are buying crap quality but they do anyway because they know, at the end of the season, they'll chuck it all away and buy something new.
I understand all of that, it's just so SAD that China can do that sort thing so much cheaper than we can.
