Kenat- the "service" type economies that I've mentioned tend to work better in smaller countries (ie those with smaller populations). Within the EU, the countries with the highest contribution from the "service" sector (however defined) are Denmark, Belgium, Luxembourg and Holland.
One thing that is interesting is that as the age of industrial societies with mass production used to be seen as bad: things like the dehumanising effect of mass production, with workers having no scope to influence working practices and the physical arduousness of manual work meant that the move to the service economy was seen as good thing in the 50's (the last thing many parents wanted for their children was to follow them into the mines or onto the shop floor). But now the mass production industrial age is seen as a sort of golden age with full employment for life....
One difficulty is that the working class used to be able to sell their physical strength (as soon as a working class person was educated enough to sell their knowledge they became middle class!), and that's no longer possible in a service economy and it's getting much harder to do in a high technology manufacturing economy too. Can a role can be found for the part of the population that used to sell their strength in the new high tech manufacturing and service economy that the UK is/ has become? Educating them all to a higher degree so that everyone can take their place in the bright new high tech future of the UK will be expensive, and in the UK, where a technical education has always been the poor relation to a academic education, difficult (for example, the low status of engineers compared to say, doctors in the UK is due to this disdain for anything that might be a bit "hands on" or technical). Or we can take the low road: with the loss of mass employment, mass production the lower skilled part of the population may be condemned to working in the low tech service economy: call centres, care homes and the like, with the same low status, low pay, low prospect for advancement as before but without the protection of low unemployment and large scale employers with fairly fixed employment relationships and large unions, in an increasingly unequal society.
Right now, it looks like the UK is headed down the low road....
