It’s not just that they spend a lot of time together, in many cases they live together.
There is of course an element of giving up, but I live in the inner east and I see plenty of people giving up here as well. This is also a socio-economic issue, they live together but also they have a far greater need to work (often more than one job) because of economic factors.
This group of outbreaks caused by the delta strain has arguably been a bigger economic issue that those of 2020 and the fact that the same level of support for individuals and businesses was not provided by the federal government as it was last year ( minus the job keeper rorting) is really disappointing imo.
