Hi Susan, get where you are coming from, but must disagree.
The 'floodgates' point is often a reference to the accepting of the Ugandan Asians who fled Idi Amin in their thousands, and came to their mother country, Britain, where they worked long and hard to set up successful businesses which gave employment to many of their fellow British Citizens.
Another 'floodgates' reference is often levelled at the Caribbeans who were invited here to do the heavy and dirty manual jobs that 'we Brits' were too proud or too good to do. They weathered vocal and physical abuse to establish themselves in a country that invited them yet treated them like a sub-species.
Of course there is the 'floodgates' that bought thousands to this country to escape German 'hospitality' during both (yes both) world wars.
And the ongoing 'floodgates' for those Commonwealth Citizens facing starvation through civil strife or natural disaster, and those European Citizens who see Britain as a shining beacon of success that they wish to become a part of (perhaps when the Tories have ruined the country enough, like they did in the early 1970's, people will be fleeing the country rather than flocking to it.)
It is too late to not have had an Empire, to not have granted citizenship to half the world in exchange for creaming off their natural resources and to capitivate their trading potential - our ancestors run up a huge bill that we must and do honour, and outside of times of extreme economic strife, we still prosper in the honouring.
Yes, there is a criminal element in almost every culture and community - indeed many emulating the seedier side of the West have become such. Take for instance the Chinese turned into drug runners by the East India Company. Again, we reap that which we sowed.
I'm pleased that in this case, justice has been done, and I would welcome justice being done time and time again, especially for the highly damaging crimes of fraud. This once perceived 'rich man's crime' used to be argued as victimless, yet in every case it is someone on the bottom rung who ends up paying. Whether as in this case by someone losing their housing place, or as with the case of Income Tax fraud where those on PAYE are left to make up the loss.
The defining mark is not of race, nor of nationality. It is of class, social status if you prefer. We are part of the flood that the elite would quell, just as soon as we have expended all our value to them.
