Its only a tiny proportion being silly about this though. The vast majority are just trying to live their lives. But it suits the government to have some scapegoats.
I don't really agree with this. Yes, probably only a tiny proportion are being really silly (attending raves for example), but I see lots of people carrying on more or less normally now. Socially distancing at the supermarket and wearing masks, but the kids out playing with the neighbours, teenagers trooping in and out of houses regularly, and going out -or staying in- for dinner/drinks with friends often. Meanwhile NPHET are saying please, please reduce your social contacts and imo it's falling on deaf ears in many cases.
Don't get me wrong, lots of people are being so careful, but lots too - and not a tiny minority - have gone back to their usual lives as much as possible. And while of course that is understandable and human nature, it really isn't in the spirit of what we have been asked to do. As a society I don't think we can absolve ourselves of blame as completely as has been suggested above.
So what do you do? Be smarter about who is high risk (excellent data is available on this, but not being widely used). Figure out a plan specifically for them.
I'm interested in knowing what this plan would entail? I'm not at all comfortable with effectively locking away the old and vulnerable to benefit the rest of society if that's what you mean, and let's face it, that seems to be the only plan anyone's come up with so far.
