The offspring would die without the stay-at-home parent. But there's no food, warmth, or shelter without the sole provider. So everyone would die without the provider

BOTH are invaluable.

Stay-at-home parent - washing clothes, dishes, shopping, cooking, cleaning, changing diapers, helping with homework, looking after sick kids, PTA meetings, taking kids to soccer, etc

Sole provider in 2024 - years of study to qualify, fighting to get into the job market, clawing your way up the ladder, earning each raise and promo for a salary a family can survive on, etc

👉 Which do you think is more difficult?

DISCLAIMER: you're right, it's not a competition. But it doesn't need to be for you to answer the question.
