This is a fluff piece written by someone in a rich bubble.
The 2 year old and 4 year old have no concept of money, the 4 year old did not "do most of the work" in a lemonade stand, and they do not have "their own money" to spend. Picking up after yourself and putting dishes in the sink are not chores, and kids this age aren't taking out the trash - of course they enjoy it when mummy does it and makes a big deal of how grown up the kids are for helping, and probably rewards then for it.
None of the ideas are innovative or relevant to most parents, and particularly not with a kids that age. This is just one rich bored parent with young kids sharing their "experiences". Pretty out of touch with reality.
But I made it a point to explain [to my children] that while sometimes being homeless can be a result of not making good choices, sometimes it's a result of not having good choices.
It smacks of empathy, which is more than I expected. Whatever one may think of the author, she’s trying to teach her children to be better, and that counts for something.
