Many Brits pay National Insurance & Income Tax all their lives and die before they reach the UK Pension age? (Like my poor sister did)

With these crazy changes, thousands & thousands more will die before reaching the pension age of 71.
This means the 'Liebour Government' dont have to pay out pensions because the people entitled are dead.
By robbing UK citizens, it will help to pay benifits & pensions for the Foriegn Invaders who came here illegally without passports or any other identification & our weak Government allowed them to stay.
As Germany discovered recently some of these Invaders were Islamist ISIS supporters.
It should have been obvious seeing thousands of these fighting age men flooding into Europe and over the channel to the UK, pretending to be escaping from whatever?
PS France's Pension age is 62 to 67 & Germany's is 65.
