Will Britain Legalize EU citiizens who moved to Britain during the last 40 years and established businesses and lives?

This is likely an important question for people who moved from other parts of Europe to England especially to London during the last 40 years. Will all these many Europeans be forced to go somewhere they have no livelihood and no business and no home?

This is one of hundreds of questions that are not being dealt with at present. And if you think about it there are hundreds if not thousands or more problems that will come from all this that will be a headache for England, For Europe and for the whole world. The stock market in the U.S. already lost any gains it made for 2016 by the way just yesterday directly because of Brexit.
