We agree on the effect on the CEO salary. but the effect is quite modest. Walmart's CEO made 22M total comp in 2019, while their workers made over 50B in the same year (25K * 2.2M employees)
so a ten cent move on the workers salary will be larger than a CEO redution to $0.
the real effect of this measure will be to stratify walmart. There will be a massive pressure to create dozens of competing regional "worker" companies. All with a GINI of 100%, all with $9 workers. By creating many of them, Walmart can be sure to keep the margins on those other companies very low.
and now most all of the $25B in labor costs for walmart are getting GREAT tax advantages since they are all operating with a GINI of 100.
Seems this was not your intent.
