are our ideas of justice incorrect?

Question

ppl think their ideas of justice are correct - but we have super-hyper-extreme injustice [pay from $1 to $1 billion for equal work] - so ppl's ideas of justice are incorrect, right?
justice produces happiness [wellbeing, high quality of life, peace, safety, democracy, liberty, friendliness, low war & crime, few problems, etc] - we have enormous injustice - so improving our ideas of justice can yield enormous happiness, yes?
[the state of happiness, not just the feeling of happiness]
if we stop paying ppl for natural gifts [which means taxing 99% of ppl to pay for paying ppl for natural gifts] we will have more happiness]?
if we stop paying ppl for benefit [which means taxing everyone else to fund the pay for benefit] & only pay for ppl's work [loss, of time & energy] we will have more happiness?
if we stop paying ppl for scarcity [which means taxing 99% to fund this pay for something which has nothing to do with the person who provides the scarce thing] we will have more happines?
