Still waiting to be told how ‘most’ of their money ends up back with the government. Yes, it may circulate in the economy but that’s not the same thing is it?
Do you need it laying out for you, step by step? I thought anyone with an ability to think logically would be able to work it out.
1) Person buys an item which may not be subject to VAT, but..
2) where do they spend the money?
3) Into a business, either in a physical shop, or on line
4) The profit the business makes from the sale pays their staff , who are taxed on their pay (and sets off a whole new spending chain as the staff spend their wages). Business owner pays themselves, leading to more to spend into the economy, and their income is taxed. Their business' net profit is taxed.
5) Business buys more stock to replace what it sells, setting off another spending chain from the business/ businesses they buy their stock from.
Do you get it now?
Of course, on the way some money is saved, which makes it inaccessible immediately to the taxman, but it will be accessible as soon as savings are spent. And we do have to account. too. for those who place their 'savings' in tax havens... but I suspect that the amount of tax tied up in savings is only a small proportion of the money circulating in the economy.
It's set out in this article in a Sankey diagram
