I don't think you can compare what happened in times when things were different compared to now. Infrastructure has been fucked for some time, through several governments. Migration is at a different level, health care continues to be a problem, in many countries with socialized systems, because of changes in use and costs, and the changes in the nature of industry have been significant. The last Labour government managed to kick the can down the road, particularly with health care, which is being paid for now, when Blair is well out of it.
The Tory plans seem largely uninspiring. On the other hand, plans from other parties don't seem to really offer any solutions either, not realistic ones.
The flow of migrants is only going to increase, and it is I think going to require an integrated approach in Europe - but it won't be what those who think the Tories are being mean will want, it may well be quite harsh indeed.
Similarly on climate issues and cars, no one with any kind of realistic idea of what it would mean to replace our current transportation needs with electric thinks that is a good solution. And renewables are not going to solve it either. Reducing pollution in city centers is a great idea, necessary even, but people are at the breaking point in terms of their family economies and that is not unique to the UK and not something voting in a new party is going to solve.
I think who will win the next election is very up in the air. Things are too volatile to make accurate predictions. Labour has the big advantage of not being in power now, they can try and give some plans that look like they might work, and don't have too much baggage around failures like the Tories do. But they are going to struggle to balance dealing with things like environmental issues, migration, the NHS, because it ill be very difficult to please those members of their voting base who want to address these whatever the cost to citizens, and reassure those same citizens that they aren't going to be personally fucked. And they just haven't managed to build much trust in general which will make that harder.
