*Yes. Why should my taxes go towards supporting those who make lifestyle choices which depend on others supporting them?
Getting pregnant is a choice. It's not something which happens to you.
So yes, I do judge.*
What about people whose circumstances change?
I once had a client with 3 young children, who had been comfortably off. Then her husband's business failed, he killed himself. Their life insurance didn't pay out, because it was suicide. She lost her home, her children were distraught (one was later diagnosed with PTSD). Her life completely fell apart.
But you'd begrudge someone like that a few pence of your hard-earned taxes.
Even if you make an exception for those who've fallen on hard times through no fault of their own, who gets the job of deciding between the "deserving" and the "undeserving" poor?
Far too much scope for value judgments there imo.
