This book is one that I not only gained a lot of information from for my latest college essay, but it was also compleatly different to other documents on the subjectt of immigration. The general argument seems to be that there was, over time, many great changes in immigration policy that essentially, didn't seem to work. The control on employment during the inter war years and pre ww1. were, it would seem, designed to create a prolaterianised immigrant population that was there ready for war time, to become soldiers and sailors and also factory workers in central Britain. However, once again, at the end of the second ww, there was dissent amongst the caucasian population and restrictions on entry as well as employment stared to be formulated again. The control on entry did'nt seem to work and Britain continued to top up its population with immigrant workers. I found this book a breath of fresh air as most of the books that we are asked to read at undergraduate level, are generally of the liberal left perspective. This book is more to the center right. It sheds a completly different light on the subject of British socio economic history.
