perplexedpirate... What exactly are you applauding?
This country is in a mess and, rightly or wrongly, the super-rich are able to avoid paying commensurate taxes. They still have to pay some just like the rest of us who work. It may be a drop in the ocean for them but that's how the system currently is. The fact remains, this country is in a financial mess and those who can't afford to have more children are paying savvy attention and not doing so.
It's risky; you and your DH work so you know this. It's easy for posters to jump on their biscuit tins and say, in pantomime villain voices... "So, only the rich can have children, eh?"... but children cost a lot of money. Who's going to pay for them? The parents!
I know you didn't raise this point but about the fathers who wander away from the children that they sire - any benefits they would have received should go directly to those children - I don't care about feckless adults who don't take responsibility. I'm guessing that feckless 'mothers' shouldn't be mentioned though so as anti-feminist as it is, let's put all the onus and responsibility on the men.
Make no mistake, this country is facing crisis, you only have to look at what your local authority cuts are going to be next year if you want a 'barometer' to give you an idea. Council tax will be going up though!
