What would have happened in Britain if it did not have the American colonies?
The American colonies were where a lot of the discontented people (religious, poor, and otherwise) of Britain seem to have gone from the 1600's to the 20th century. Which likely served as a nice safety valve for the British government. Without the British colonies of N. America would Britain have a Glorious Revolution or would Britain just send more people to Africa and maybe Asia?
And I realize that Britain would likely push to get a piece of American the American pie, but I'm more interested what you guys think would happen on the British Isles.
