I'm not quite sure what to respond to this, as it seems you don't actually have anything remotely resembling a clue about what you are arguing.
First of all, you need to lose the tone, it reflects badly on you and taints your argument.
Do you understand what a visa is? Do you grasp the concept that certain countries waiver the visa, so you have freedom to travel there, but their border isn't open to everyone - to get a job you have to apply for a work permit. New Zealand is one example. We can freely travel there, but we can't freely get a job
Visa waivers are unworkable in UK scenario if you want to maintain work permits. This isn't New Zealand, the numbers are 12-15 times higher. 32 million visitors a year and 24 million of them are from Europe. The country has no national ID, no centralised records, even stuff like Work Registration Scheme currently takes weeks to arrange. Creating administration dedicated only to work permits outside of immigration forces is something you don't want to even imagine. Tories tried something like this in nineties, where HM Home Office had an external work permit control system based on separate document (a green book of some description) maintained by independent office called Alien Registration Bureau. Immigration control officials back then had about 16 separate versions of passport stamps - different scenario for time limited right to remain with no right to work, different one for time limited right to remain with no right to work unless permitted by secretary of state, different stamp for students who needed part time work permit to support themselves, different for students who needed part time work permit to do work experience for Uni etc etc. Every person that entered the country for more than a month and needed work permit had to attend additional interview inside the country and were issued special document detailing conditions of their stay, permits and exclusions to both, complete with copies of passport stamps. In the end the system was abandoned because it was simply unworkable. The sheer volume of people was one thing, but necessity for details and records would drag the proceedings for weeks and rise to epic proportions. People would often go to embassy and get new, clean passports issued just to restart the paperwork without the need for two lorries of paperwork to be recalled from Croydon. And then you had appeals, reviews, court orders. Every time your foreign girlfriend wanted to return home for Xmas she had to gather all the papers, letters from school, proof of residence, statements proving she can support herself etc etc. Absolute nightmare. It literally created entire black economy of illegal workers and camps and the less sinister but equally dodgy arrangements of gap year holidays where the entire buses full of passengers would disappear into the night on the first parking lot after Dover as people couldn't waste their life in Kafkesque administrative machinery just to come in, do some hotel or bar work and spend the rest of the summer sight seeing around the country.
Anyway, back to the topic. Visa waivers. You cannot begin to imagine the sheer size of administrative force you need to create to keep records and maintain work permits, extensions and revisions for visitors inside the country with traffic and popularity of US but the size of UK, plus you also need proper enforcement agency to monitor and control job market, otherwise you will just create gigantic black market where no questions are asked and no tax is paid, since as customer you won't be able to differentiate between French person with British passport, French person with resident status, French person with work permit and French person without work permit performing their duties illegally unless you somehow provide the entire nation with IDs and make it compulsory to carry them everywhere. And that's not going to be easy.
