Who are you to say whether any particular amount of money or wealth is appropriate for anyone?
Do you propose taxing only large retailers like Walmart or also the large multinational companies that manufacture the goods sold by Walmart and all those small businesses, e.g., Colgate, Proctor and Gamble, Kraft Foods, Jockey, etc. If you also tax the manufacturer, the price it charges Walmart and the small businesses will go up and both retailers - whether large or small - will have to raise the price of what the consumer wants to buy.
The only thing that will help small business, the middle class and just about everyone else is lower taxes.
Spot on. Materials cost goes up, prices go up on the finished product. Prices go up on the finished product, prices go up in the store.
These things are not made by some replicator out of thin air - they need raw materials, transportation, various skill level workers, machinery (with it's accompanying depreciation and maintenance), stockers, checkout staff, drivers, warehouse staff. Every one of which needs paying for, before the government take their cut in taxes and excise duty.
The profit raked in by the "fat cat" billionaires is negligible compared to the total required to pay everyone else.
PS - Not to make suggestions, but everything from post 18 onward might be better split from this thread and given it's own.
