A much simpler tax system would be to tax everyone like hedge fund fees. You pay 2% tax on all assets and 20% on profits those assets generate. Regardless of asset type (if it is worth money and can be traded, it gets taxed). Ditch everything else (especially regressive taxes like VATs) and keep a progressive income tax. This 'everyone' is individuals because someone, somewhere owns the assets.

Note that those are the pre-2008 hedge fund fees and the fees are presently less than that.
