Oh wait, there are multiple concert visitors, and a kindergarden group has multiple kids per carer there.
Yes, a very made up number, Taylor Swift tickets for this year's tour were between $50 on the low end and $500 on the high end (plus fees) for the initial sale[1], and averaged $1600 in the resale market, with some tickets for that were close to the stage selling for up to $6300[2].

$5000/mo with 4 kids is only $1250/mo/kid or only about $300/week/kid. Plus you don't have to go drop off or pick up your kids at a separate facility, as usually the nanny comes to the children.
As a child care provider working as a nanny you'd make $60k/year. Can you make $60k/year working at a child care facility?
