The Greens wealth tax

[king1]

On their $240K annual income, they pay approx. $61K income tax; they also donate very generously to various charities (I see the donation receipts).  Under the Greens' proposed policy, their income tax would reduce to about $57K, but they'd have an additional $150K "wealth tax" to pay, so total tax would be $207,000, leaving them $33K/year or about $635/week to live on.

are they expected to come up with this 150K at the time do you think, or is this likely to be deferred until the asset is sold?

Will they really be living on $635/week?
