You could've read the very next sentence, which makes the point the first sentence set up:

> Assets must be accounted for when calculating wealth, so the tax service will be required to track and value assets including vehicles, homes, and material good etc. for every citizen to see if the wealth tax would apply to them -- if we didn't report material goods, the wealthy could sock money away in expensive cars, artworks, jewelry and other material non-real-estate assets as they already do for investment.
