The incident demonstrates all too clearly that Wales is simply too used to playing the victim and receiving handouts; it doesn't have the mindset to run its national affairs as a cohesive whole. The purpose of these thoughts is to offer, from a personal perspective, some circumstances which might contribute to this, and what might be done to make things a little better.
There are restrictions imposed by geography and the existing communications infrastructure. Mountains, by and large, tend to stay where they are - movement on geological timescales is of no great value to the present population - and any grand design for the future of the country should recognise this. Wales is, partly as a result of its geography, not well served by road or rail. The A55 from the English border to Holyhead is a fine artery, when great chunks of it aren't closed, and industrial development is creeping along the North Wales corridor. That will bring its own problems as imported management puts pressure on a housing market already inflated by what might clumsily be called the non-indigenous population. The authorities in Wales, however, seem blinkered and only capable of seeing this influx of population as a problem, ignoring the opportunity that it represents. Many of these people have spare capital and ways can be found - can be quite easily found - to encourage investment of part of that spare capital in the stock of locally owned small businesses.
The transport links are primarily the already mentioned A55, the M4 corridor across South Wales and the central routes to Aberystwyth and Cardigan Bay. Anyone who has ever driven from one end of Wales to the other knows that it is not easy - England has the M1, M6 and A1, dualled from London to the Scottish border, and Scotland has its share of equally good roads. Even the A9 has enough dualled sections to make it a pleasure to use. Wales has the A470, for most of its length no better than a country lane. Rail links in Wales are slow and expensive, and most unlikely to improve, and the country is really too small to make regular air transport worthwhile. Unless, that is, some really determined entrepreneur can duplicate the sort of services that island-hop in various parts of the world.
