Modern “neoliberal” capitalism requires constantly increasing velocity and atomisation of transactions. A #robinhoodtax at 0.5% is nominal and fair. Capital cannot remain stateless and boarderless.
Consider what VAT is: a regressive tax on the transaction of purchasing goods set at 20% (with exceptions). 0.5% on financial transactions is fair and reasonable, will raise £26bn.
There is already a transaction tax, it’s just the proceeds for this go to the big financial institutions. Every transaction has a cost. That’s how modern capitalism works. 0.5% per transaction is effectively a micro payment. Remember these banks make hundreds of billions, and caused a world wide financial crash. It’s about time we stopped being so deferential to them and make capital contribute to the security of the societies they effectively leech off.
