This is a very interesting topic and I feel very hard to make ends of.
For example, you can compare local money (brits spending money in UK) vs foreign money (foreigners coming to UK for holidays) and get a part of the picture. On the other hand, local money are going to be spent in smaller towns, but the foreign money mostly go to large centres, London, Manchester, Liverpool, Glasgow etc. Then there are the amounts involved, 500gbp in London will buy say, a weekend for a couple, therefore employing not really that many people (cook, bartender, server, cleaner etc). The same amount will buy a weekend on the east coast for quite a few more people, therefore requiring more support personnel (hence, more jobs).
