3T - Oh wow, talk about jingoistic right wing rhetoric. Hot air, no substance.
There is nothing inherently "anti-british" about being left of centre, despite your rather feeble attempt to link the two. Only in the minds of the most rabidly nationalistic right winger is this even remotely true.
Its the economists, the politicians, the commentators and observers who say we do not "manufacture things", and it is always a qualified comment anyway, comparing now to times past.
If you look at any decadal breakdown of the trends within british economic activity,ordered by market segment, you will notice the decline in the contribution toward the GDP that manufacturing represents, and a shift towards the service sector and banking. This is not in dispute. This is not a political assessment. It is factual. Its not even unique to Britain, although the shift is more marked because of our banking and financial services sector.
And given that many of " the left" in this country would be comprised of union members, it is they who would be most keen on promoting our manufacturing industries and urging more, if only for narrow self-interest reasons, since an increase in the manufacturing sector might imply more skilled and semi-skilled labouring jobs. On that basis alone, your hypothesis would be pretty unlikely!
Such a partisan question, without any credible base to it at all...Just another of your periodic swipes at "The Left", it seems.
