The UK government has decided that senior executives can temporarily leave quarantine in England if they are undertaking business activities which are likely to be of significant economic benefit to the UK.
(Hopefully, the virus will be informed and will conduct itself accordingly)
I suspect that many of the activities which in reality could benefit the UK economy greatly do not meet the requirements of this ruling by the Department for Business, Industry, and Industrial Strategy and hence are not viewed by the government as truly important.
An extremely successful startup CEO once remarked to me that ‘the secret to startups is that you have very smart people working on very small things.” By ‘small’, he definitely did not mean ‘unimportant’, rather, that the activity…whatever its future potential…was still not yet large enough in revenue and perhaps also in public awareness to get proper attention at the senior levels of a typical large corporation. (And by ‘smart’, he didn’t mean just IQ, but the whole range of business skills)
Governments will always tend to focus on things which are large, or fashionable, or both, and will more often than not act as inhibitors toward true innovations.
