Now, frankly Luke, do you buy "Made in the UK" products only, or do you prefer the cheaper Made in China, Pakistan, India, Vietnam? When you first bought your cheaper "Made in China" shoes, did you pocket your savings or did you mail them to low-paid workers in China? So, who is to blame?
Companies that moved production to countries with cheap labour and reaped the benefits until competition did the same, or western customers who benefited from the beginning, but are now starting to feel the pinch? The moment the people in Europe and North America preferred those "Made in China" shoes to "Made in the UK", they started the very process you complain about now. By the way, globalization also brings gradual equalization in living standards to people in different countries, so there is your positive.
