Thats because its not adequate, if you intend to work and live here long term or even jobseek you should have a visa and permission to do that. We should know who is intending to enter the work place and who intends to live here long term. If you simply want to come here for a few months, hang out with your family and have a bit of a jolly where you have no intention of working or remaining long term then the visa waiver system allows for this, the duration allowance of which is dependant on your nationality. Which bit of this are your struggling to understand.
pasta - lovely idea this having people from all over the world have visas to come and work here etc, etc as part of your global immigration policy that you'd like. A couple of practical issues though:
Outside of The EU, most of the rest of the world is made up of developing countries. I appreciate some of those countries already have visa free travel to The UK, such as Botswana and Namibia and some don't such as Pakistan and Bangladesh. There's many problems developing countries all have and share, but 2 problems in particular are poverty and corruption. Poverty the world over leads to crime and corruption just makes it more easy to do. Even in countries that are deemed to be less corrupt than others, such as Namibia and Botswana, if you were arrested for drink driving prior to Christmas for example, no matter how drunk you were, you'd just pay the arresting officer off in the form of a bribe and everyone's happy.
I find this intriguing that Batswana nationals now enjoy visa free travel to The UK now. It's a recent change. Like British nationals travelling to the US with criminal convictions, Batswana nationals are supposed to apply for a visa at The British High Commission if they have one, but there's no way they or The Border Force here would ultimately have a clue if someone did. Then again it would be similar issue with actually applying for a visa to work here - The BPS at Central Police Station in Gaborone, located at the bottom of Queens Road in Main Mall from the rather shabby, run down British High Commission building at the other end, would just issue a 'PCC' showing no criminal convictions with no problems and if there were, you'd be amazed at what doors can open for you by passing over a few extra Pula banknotes. As Botswana is deemed to be relatively corrupt free both in African and global developing country terms, I do wonder what practices go on elsewhere, such as in Pakistan and Bangladesh.
Still, global Britain post Brexit - less Polish and Belgians, more Pakistanis and Bangladeshis.
