71% agree with a new wealth tax on earnings above £250,000;
Wealth is a stock, income or earnings a flow.
A wealth tax is thus a tax on the stock of stuff that people already have. A tax on earnings would be a tax on the flow and would be an earnings or an income tax.
A "wealth tax on earnings" is thus simply a stupidity. Proposed by those too stupid or too ignorant to know the difference.
Sigh, if these bongheads cannot even get these simple thing correct then what hope for their glorious ideas about taking us back to 1976 style corporatism?
