As someone said above, if you feel that way then that's fine, give up your job and stay at home. That's always an option you have regardless of what anyone else does.
For a lot of people returning to work will be essential though as they're in circumstances that won't allow them to feck their job and still manage somehow. For them it isn't the dichotomy you're presenting it as. Not going back to work also rolls the dice with their family's safety, in many cases with worse odds than going back to work does. Which makes "at what cost?" a rather moot response when people point out that reality. If you're in a position to "manage somehow" after giving up your job then you're luckier than a lot of other people.
Here in Japan the suicide rate is already high although not as high as that in South Korea. Essentially fear of other people's opinions and judgement and an obsession with saving face plays a big role, but even with Japan's limited State of Emergency the economic pain is biting. I dread to think of the human toll this is taking on ordinary workers especially those with blue collar jobs such as making food, delivering it, working full time in supermarkets and stores, labourers, etc.
The famous Tokyo Tsukiji Fish Market moved last year to an area called Toyosu which lacks Tsukiji's charms and already had seen a dive in visitors. The other day I read a Japanese news article where workers in the market said in despair that they can't make a living as it has been shut down just like many other attractions, businesses, shopping malls, theatres, etc etc. Tokyo is home to a big theatre industry and there are so many actors/musicians who are paid barely liveable wages in the first place and of course all of that is shut down.
It's cruel and it's going to get crueller. People who have never lived in Japan or have been the privileged big international company employees or the sheltered overpaid foreign service employees have no idea of how low salaries and wages are in Japan including in the most expensive city of all, Tokyo. Japanese complain about how expensive Oz is but salaries/wages are much higher. For some reason the politicians in Japan think that a family with 1 or 2 kids can pay tax and get by on an income of 220,000 yen per month. The income is before tax. That's about 2,200 Oz dollars per month.
That's barely enough for single people and while many Aussies would say 'Oh but welfare is that low' in Oz, the fact is in Japan you are actually paying real taxes on that kind of income - for starters national health insurance each month which is usually more than what you'd pay per month for private health insurance in Australia. You also pay a flat rate of 15,000 plus yen for the national pension each month which is about 150 Oz dollars plus so called citizen's tax 4 times a year which slugs somebody on the salary I mentioned for over 1,000 dollars.
You also pay income tax on that paltry income. No discounts on transportation, no utilities help or rent relief etc. People with children do get child support but it's not much. As for people with no children, and single people, especially foreigners, basically the system doesn't care about them but it does want their money.
The Japanese also have no culture of charity shops, thrift shops to help lower income and special needs people, no culture of giving to somebody who is not connected to you, etc. There are volunteers for different things but their assistance is very small at the best of times, they don't have fund raisers for needy people, there are no established food banks here, a tiny number of volunteers giving a few rice balls to the homeless and semi-homeless who live in horrendous conditions including the oldest homeless you'll find in a first world country is no comparison, and there is the prevailing idea that people should save their money and not beg from the state or society.
Even this semi-voluntary semi-lockdown here in Tokyo is killing the economy of ordinary to low income workers, smaller business owners and sadly I expect the suicides will jump as there is no real program to compensate them and the one time handout of a few thousand dollars in Japanese yen will only go so far for those who are lucky enough to get it. The bar will be set too high as it always is. And don't even mention households where are no Japanese. I've never received a single yen from the J Gov anytime as somebody who pays a considerable amount of tax proportionate to my income.
I'm used to that by now but the twitter from a Japanese poliitician in the present Abe Government still angered me. This POS tweeted that foreigners should go home and their countries should look after them. She didn't say international students who fall into a grey area - she said people like me who have paid a lot of tax for years here including expensive health insurance payments each month. I believe in national health systems and it's a necessary obligation but why members of this goverment are allowed to publicly insult people who are keeping their society running along with the Japanese, is beyond me.
