The point in Polyamory is for all to get brought up, for all to have a better life together. If not then that is not Polyamory! There is a time to have a secret affair but it's just better to just come out! If your partner doesn't seem to care about your needs treating you like their property I would see as co dependency in a way.
All should be Contributing to their society as all should be working to make life better for all. If there is one a stay home partner and the others works then they are only making half or less of their pay as the other half goes to cover the one not working, That's not social mobility more of a decline if long-term! And so is the point of Polyamory in these times to save each other by going up!
