You do not understand the problem. Where you alive at the time? I was and there was a big push for Scottish independence, Labour heartland seats falling. Blair decided the best way to head off the full independence was to give them some measure of control while leaving the important bits for Westminster. To ensure there was not a power base divide, the voting for the new Parliament was engineered in such a way that no party should ever get a majority. Wales had to get something similar as both Scotland and NI had some control over their affairs.
In the last election. 2021, under the first ballot in Scotland which is the traditional Westminster style constituency fptp, the results were 62 SNP, 5 Tory 4 LD and 2 Labour. If it had been left as such then there would be more problems but the second regional vote in both Wales and Scotland ensure minor parties are over-represented.
Both countries still, with some small exceptions, rely on the block grant from Westminster for funding. Both countries have seen their money cut back over the past 12 years. Services such as the NHS in Wales will obviousy be hit. Your vitriol over Covid in Wales fails to highlight the most important part of Covid restrictions, which is what the people do. If people do not help you will get spread. It has been shown many times that poverty increases health problems. Wales has still not recovered from mine and steel closures.
