"We've had rising inequality in this country since 1990, which was the year of the Mother of all Budgets, and 27 years on there is no evidence whatsoever of any economic trickle down effect," he said.
Mr Morgan said TOP's asset tax policy would fix the inequality in the country's tax system by ensuring assets were taxed. This would also increase wealth fairness.
"Closing this tax loophole will allow us to cut income taxes by up to 30 per cent, leaving 80 per cent of people better off," he said.
Mr Morgan said TOP would slash the tax rates of salaries and wages and ask the owners of assets to pay more.
"This is nothing to do with capital gains tax. I hate capital gains tax. Think of it as a wealth tax if you would," he said.
"Our tax policy may appear radical, but not by international standards as most countries have a wealth or asset tax. We have to do something as the gap between the rich and the poor is growing," he said.
