From 2014 to 2018, such households saw their net worth expand by about $65,000 after taxes on average, mostly due to the rise in value of their homes. These include raising the tax rates on people making over $400,000 and bumping the top income tax rate from 37% to 39.6%, with a top rate for long-term capital gains to match that. It's a completely different picture for middle-class Americans, for example, wage earners in their early 40s who have amassed a typical amount of wealth for people their age. Their wealth derives from the skyrocketing value of their assets, like stock and property. Can you explain how this system works?
value of assets is the estimated value of the skyrocketing of their assets.
( z0 value :ARG1 ( z1 asset ) :ARG2 ( z2 value :ARG1 ( z3 soar :ARG1 ( z4 asset :poss ( z5 they ) ) ) :ARG1-of ( z6 estimate ) ) )
(z0 / value-01
    :ARG1 (z1 / asset)
    :ARG2 (z2 / value-01
              :ARG1 (z3 / soar-01
                        :ARG1 (z4 / asset
                                  :poss (z5 / they)))
              :ARG1-of (z6 / estimate-01)))
value of assets is the estimated value of the skyrocketing of their assets .
z0 :ARG1 z1
z2 :ARG1-of z6
z0 :ARG2 z2
z2 :ARG1 z3
z4 :poss z5
z3 :ARG1 z4
