Yes, yes a thousand times yes. The older girls are like 12 and 13. This is the age that kids start babysitting other people's kids. The girls could step it up at home to help their mom be able to teach a few nights a week, presumably at a dance studio that is closer to their home than Philadelphia. Perhaps they would need someone to pick them up from school if it is a transportation issue. But once they get home- they can chill out until their mom gets home from dance class. It's not like Beth teaches until midnight or whatever. Most working families in America have to figure this shit out, and most don't have the advantage of living in a huge ass house with no mortgage (Randall said he bought that pig for cash in an earlier episode bragging to dying William about how successful Randall became even though William failed him so hard). A dance instructor's schedule could actually work out really well for them if Randall would stop being such a little bitch about controlling everything. Don't we all know families where one of the parents is a musician, or an ER nurse, or a yoga instructor, or a waiter or whatever else and their schedule isn't 9-5? There are trade-offs, for instance, Beth would be around more during the day, enabling her to get ahead on household chores, school events, etc. and has the added bonus of not having to be all done-up for work at a job that starts at 9am. The privilege of all of the people on this show has become obnoxious.
