So saving the money they would be otherwise be spending on supporting their lifestyle is somehow more important to them and better spent than if they were caring for their child?
What if your parents took this attitude? What if you were aborted/killed during gestation, so your parents can spend the money on fast cars or expensive clothes?
Even if you cannot financially support your child (which you should have seriously considered before you even had sex, the aim of which biologically is to procure children, not give pleasure) there are other options. If you play with fire, you're going to get burnt.
There are government programs to support people trying to care for a child. You can ask if your parents will help you support the child (some people's parents could and would be willing to help). Even if you're circumstances are dire, the baby can always be given up to adoption. Tragic, but preferable than abortion and at least it gives the child the fair shot at life which it deserves. Do you agree?
