People who say "No one expected this" - well, no, most of us didn't think about it day-to-day, but it was known that a pandemic was likely to hit at some point, and governments should be prepared for things like this. Not necessarily in great detail, but it should have been on their radar. It's like when any disaster happens - say a school has a fire and the building can't be used - Councils have plans in place for alternative buildings that can be fitted out; they don't go "Oh flip, we're going to have to find somewhere" and then there just happens to be an empty council building not too far away that can be used - that building may well have been kept empty for emergency use.
For instance, look at the PPE situation. A plan would have laid out what needed to be acquired, how it would be distributed, what kinds of companies have these supply lines already etc. When the pandemic appeared on the horizon, the government could have gone to companies and asked them to get plans in place, ordered preliminary supplies etc. Then as things got more serious they should have been working with these suppliers to really get things moving, so that PPE was here before it was needed.
Instead, they waited until it was too late, then handed contracts (apparently worth billions) to companies with no experience in this area, which happened to be run by their mates.
Once things really kicked off, they didn't do any better. Schools, for instance - sending kids back for 1 day after Christmas (hence spreading infection) and then closing everything. Why wasn't there a plan in place from August, to say that if rates were high in December then things would close early and reopen later?
This government has been a shambles. They have used the excuse that they have been taken completely by surprise, but they should not have been. It is the job of government to have plans in place for situations like this. They have failed to do their jobs, and made a bad situation considerably worse.
