But you see they do affect you.....
If you are in a car accident and need urgent medical attention it will be an NHS ambulance taking you to an NHS A&E. BUPA aren't going to send out a little private ambulance for you with your own monogrammed slippers warming in the back.
If you swim in the sea and get sick because of sewage in the water you will wish you'd cared more about the environment.
If you don't have food to eat because the environment has been ruined you'll wish you'd cared more.
Those children will be the people looking after you and your DH when you are in a care home.
Oh, and not all would get away with corruption given the chance. Millions of people have stronger principles than you.
