From a personal point of view, it was glorious. I met DH at the end of 1997 and moved from Middlesex to Gloucestershire when we got engaged in 1998, aged 24. Previously, I'd been living in a house share with 4 schoolfriends, we were all working / training in professional jobs and thought we were living This Life.
When I moved to be with DH, I took a paycut of 1/3 to move to a regional office of an accountancy firm, and could still afford to live and save for a wedding. We went to France without even thinking about it, really, that summer. So easy.
We got married in 1999 and bought a 2 bed flat while I was still earning £13k, our mortgage was £340 a month. DH was part of the dot com bubble and had home internet from when I met him, albeit dialup. Our first joint computer cost £1,000.
It was brilliant partly because we were young, in love, solvent with disposable income and only had ourselves to please.
On the other hand, the world had felt so hopeful since the labour landslide in 1997. You could see things were genuinely getting better for the poorest and most disavdantaged in society, there were fewer rough sleepers, more support for early childhood. Whatever one thinks of Gordon Brown as a PM, as Chancellor I felt we had someone who knew how ecomonies worked, rather than just funnelling money where it has always gone i.e. into private fat cats' pockets. There was a Democrat in the White House, with every expectation of another one at the next Presidential Election; the Good Friday Peace Agreement was brokered and the need to be watchful in public areas in cities was gone. The Twenty First Century was coming, and it was going to be GREAT.
