Virtually nobody is a British subject, we are citizens.
There are only two cases where you can be a British subject: if you were born in the Republic of Ireland before 1949 and claimed British subject status before 1983, or if you were born in a British colony that gained independence but you didn't become a citizen of the new country.
I'm now 38 years old and have seen little evidence to support your statement, either in the UK or elsewhere.
Most people seem _totally_ okay with members of their ruling class being drone-murdering, tax-thieving, law-breaking, crotch-grabbing assholes.
If only the subjects of the UK had a spine, as a people, and the willingness to confront the dire evil that has usurped their political infrastructure .. alas, they don't. A nation of cowards, really.
A nation of sheep perhaps but not a nation of cowards.
Not to mention a significant portion of the society appears to be perfectly aligned with the need for a total surveillance state, due to an endemic national fear that, perhaps, the imperial acts committed in their name will come home to roost..
Not sure how you arrived at that conclusion, most people I know don't know much about what we did during the age of empire and the rest broadly think Empire was a good thing for the countries we conquered.
