I don't expect taxation to ever be "fixed".I'm not sure either and I would support either of those two adjustments and see what happens. I do not expect the tax situation to be fixed in a single presidential term given how slow it moves. But a step in that direction would be something I support.
Those clamoring the loudest know the least.
One of the worst is taxing capital gains without adjusting for inflation.
You bought a commercial property in 1990 for $1,000,000.
You sold it in 2000 for $2,000,000.
Despite what government says about the CPI, inflation during
that period was 7.2% per year. This means that a dollar in 1990
is worth only $.50 in 2000. (1.072 to the 10th power = 2)
Simplifying assumptions:
Let's ignore expenses like commissions, transfer taxes, etc.
Let's also say that you never took any depreciation.
The IRS would say that you made a $1,000,000 profit.
But your $2,000,000 cash in 2000 is worth the same as
$1,000,000 in 1990. You made no economic profit.
But you're taxed upon the phantom profit (due to currency
devaluation) of the dollar difference in basis & sale price.
Why should you pay tax on the loss of value of the dollar?
Capital gains tax should be indexed for inflation.
Why should capital gains be taxed at different rates which
depend upon the kind of asset, eg, stocks vs coins?
