>we think that is because of the infrastructure is already in place in those countries
A decent ADSL connection is still enough for most people. When it comes down to it it's hard to find anything that needs more a dozen Mb/s of throughput even for a busy family. IPTV might..but then we already have more than enough choice in TV provision. FreeSat, FreeView, Sky, VM. Yet another bloody TV service is hardly going to kick start the economy.
Even then TV isn't really that much of a bandwidth hog. You can get adequate HDTV in less than 10Mb/s even when encoding live (ask the BBC). With offline compression you can probably get that down a lot further. I reckon anyone on FTTC should already have enough bandwidth to feed the main TV in HD and a couple of kid's TVs in SD. Those on a top-notch FTTC link can probably feed several TVs in HD.
The people that really need sorting out in the UK are those on longer lines. Houses getting less than 10Mb/s. Those people need help. I think FTTC is a reasonable compromise and I do wish it could be targeted at those on lower speeds first. Unfortunately economics and geography make that financially unviable :(
Long term I think the UK is doing 'okay' for most people. We are making good use of what we already have and are gradually upgrading it. We just need to find a way to cover those areas that economically problematic. Stop concentrating on high speeds and look at a way to boost those at the bottom.
