"Shared sacrifice" is a dumb concept. If you think the present system is scaled too favourably to the rich, you should support sacrifices to made by the rich before the non-rich. If you think the present tax system is too unfavourable to the rich, you should support sacrifices made by the non-rich before the rich. Yet again status quo bias pervades, with people not really having any coherent philosophy of economic fairness to guide their decisions.
I'd go a bit further - anyone who suggests calling the rich to account for their crimes without
demanding the proper punishment is really just whistling Dixie. Calling for sacrifices is just like asking Simon Legree 'not to beat us so much' or to give us a little more cornpone. The appropriate response to the crimes of the slaveowner is to do one's best to kill him and all his heirs and dispossess them of their lands.
