Stay at home parenting isn't hard

I don't think it's hard. Necessary but not hard.

For most of the kid's life they're in school half of the day. Modern technology has made household chores incredibly easy and with access to modern entertainment you can do things you enjoy (music, TV, Youtube, E-books) while doing household chores. As children age, the responsibilities only get easier.

Are there moments that are hard? Sure, but in totality it's not hard, and I'd like to hear arguments as to why people claim it is.
