Raising a child costs between $13k[2] and $35k[1] per year in the USA – depending on where you live and who you ask.
With a minimum wage job ($7.25/hr) you need to work about 5 to 13 hours per day to make that much – before taxes.

Income can't be irrelevant, you do need to provide for that child. Only if poor people didn't have a problem to do so would it be irrelevant.
If a woman abort because she really doesn't want the financial trouble, it's not wrong. Furthermore, having the right to choose means she could even have bad reasons without it being wrong.
Now if you ask me, the meme isn't really about the choice itself. Poor people often choose to have a kid regardless, most women are wise enough to know it's worth it. I think the real problem is how harder it is for them to take that choice.
