Doubt this would work practically because the tax is on profits and the owners can just reduce the clubs taxable income by giving themselves enormous salaries which would then be taxed in a normal way. Whilst tax is the prerogative of the state, they can't just levy a specific tax on 6 companies receiving income from sports related activities.My suggestion in another thread was simply to impose a tax on earnings from the ESL, like 90% income tax and 100% tax on gate receipts at ESL matches.
Taxation is the prerogative of the state and can’t be challenged, these clubs want to be filthy rich, well they can hand over the excess wealth back to society. It would have the support of the population, especially with the huge holes in government budgets due to Covid-19
