Unfortunately there is not a once size fits all solution to the tax issues we face. If each State wanted to individualize their own taxes and if it were humanly possible to get rid of the IRS all together than hmmm maybe. I wish I had an answer.
In South Africa that would be too little. After calculating everything (Income tax, VAT, Fuel levy..etc) we give over 60% of our income to the tax man
Top 1% would still find a way to avoid it. Better approach is VAT.
What if they were? The Ultra rich would still hide their money and "special groups" would claim exemptions.. Remember to tax the churches too.
As with most what if questions, it's not going to fly
you on drugs or just plain stupid.
This would be not be a good idea. The lower paid workers would be disadvantaged compared to the high income earners
