However, I think we can make a reasonable assumption that it would still be a leading world economy and that on the basis of its high level of productivity and the quality of its goods, together with the additional advantage of being able to control the value of the DM, that it would still have a trading surplus.
Whilst looking for an economist’s point of view I found this article in The Guardian:
