Taxing Pollution

Auto licenses  are a tax, levied to pay (in part) for building and maintaining our streets and highways.  I suppose that various states--and various countries--have formulae for assessing  this tax.  But none--to my knowledge--taxes what most should be taxed.

Taxes for transportation of freight and  produce, and mass transportation for people are not what I am thinking about.  I am thinking (at the moment) solely about private automobiles.

Why not develop a formula for taxing private automobiles that would be based on the length, weight, horsepower, and fuel consumption of each vehicle.  Such a formula would tax pollution.  And it would tax the wealthy or pretend-wealthy who drive obscenely big cars.  If the tax were high enough, maybe the prestige-seeking pretend-wealthy would quit buying obscene cars.  Presumably, the wealthy would not be bothered--unless we made the tax so high that even they would be threatened.

Why not tax luxury vehicles--from limousines to sports cars--at a special "arrogance rate," high enough to make even the rich folks think (if that is possible).

If we succeeded at this, we might even get the sense and the courage to start taxing wealth directly--at perhaps 90% on gross income of more than one million dollars or euros or pounds a year, and a 90% annual tax on all accumulated wealth in excess of ten million dollars or euros or pounds.

Of course, we would have to prohibit these tax revenues from being spent on the military, or on salary raises and additional perquisites for members of governments, or the building of new government buildings, or the creation of new government bureaucracies.

Why not?  The only reason I can think of for not enacting such laws is greed.

Greed is the opposite of freedom, love, community, commonwealth, care, charity, civilisation, society, decency, and peace. 

So shouldn't we all oppose greed, individually and collectively--as a society?
