The solution is a radical design of the tax system. We need a system which is simple, practical and deters only activities which society deems undesirable.
Ah....but there's the rub. What does society deem undesirable? Cigarettes? Alcohol? Marijuana? I suggest that the activity which is most undesirable yet prevalent is the emission of gases causing climate change.
Therefore, our tax system should be adjusted to place the majority burden of taxation on activities which emit CO2.
Commuters will scream: “but I need my car to get to work. How will I manage if my fuel bill is a thousand pounds a month?” - My repost would be: If income tax and National Insurance were abolished then you could afford to pay a thousand pounds for fuel......but you would have huge incentive to DO SOMETHING about climate change rather than talking about it.
