Take a few moments to look at this website which gives details about the debt problem Britain has today. If it doesn't scare you, it should. Because today Britain rolled over the Trillion pound mark. As the website says, this debt is real and it needs to be paid back. This debt is not any different from the credit cards that we all have; eventually it catches up with you.
And if anybody ever tells you that the austerity measures are not necessary or urgent, just pop back and see how much our debt is at that time.
