I think that RS has been pretty responsible - has tried to support as many people as possible without the scheme being open to fraud. You can't give away money to those who operate limited companies easily because it is hard to tell, via the tax system, who is an owner/operator and who is an investor - obviously you want to support those who are running companies but you might not want to give public money to prop up people's share portfolios, so guaranteeing a dividend stream is hard without auditing the individual arrangements of a lot of companies, which is very difficult and cumbersome. And it isn't unfair to point out the lower tax burden on those people who operate through a limited company both historically and likely into the future (contrast the self employed people who don't incorporate who RS has already warned that the price of supporting them now is more tax later).
But RS has been surprised by the uptake - under government guidance people who are not key workers should largely be going to work if they can't wfh but this has been ignored. The number of threads on MN with people basically wanting to sit at home and/or mad keyboard warriors telling people that their bosses were wrong to ask them to come in was amazing, but what do you expect when the BBC reported that you could only leave the house for essential work on the news immediately after Bojo's announcement of something completely different!!
In three/four weeks' time, I fully expect that we will be told that, work from home if you can, but everyone should be going to work. And we will see some businesses being told they can open in a measured way again. Because we can't afford otherwise. Like on the schools thread, you will see people say "how is it fair that the government are forcing us to go to work/school when we could catch this killer virus", completely missing the point that no country is deploying a strategy that entirely prevents their population from getting the virus before a vaccine is available. That would be nuts. Everyone, everyone, is trying to balance their healthcare capacity so that those who get it can be treated properly and resources are not rationed so that people die who should have lived - entirely different. Look at Denmark - schools back open again.
