Heck, when the tax rates were that high, we had: * the GI bill, enabling all vets to go to college for free, * built road systems like the Interstate highway system * built schools * built libraries * WENT TO THE MOON.
Seriously, if you want to complain, you will find waste in absolutely ANY large organization, corporate, philanthropic or govt. -- it just comes with scale -- there's economies of scale and inefficiencies of scale.
But it does not follow from the existence of nontrivial inefficiency/waste/fraud/etc. that large organizations and their projects are therefore worthless; only that improvements might be sought.
I'm not against it, but I wonder at it's effectiveness, as regs are subject to many of the same loopholes, exclusions, and workarounds as taxes, along with regulatory capture (see FCC and Net Neutrality).
Neither is perfect, and I think we need both.
E.g., rags/taxes to cap CxO pay multiples -- so they have to bring up the pay of the average worker if they want higher exec pay. Regs for minimum wage above the poverty line...
either way, I think we need to get the masses of idle capital back into the middle class if we want a robust country and society.
While it wouldn't really solve the activist investor issue, I favor a strongly time-based capital gains tax system, designed to favor long-term investment, over short-term financial extraction. The rate table might resemble: <1 minute = 95% cap gains tax rate
<1 hour = 80%
<1 day = 70%
<1 week = 60%
<1 mth = 50%
<1 qtr = 40%
<1 year = 30%
<2 yrs = 20%
<5 yrs = 10%
<10 yrs = 5%
>10yrs = 0
Obviously a mere first-draft, subject to tuning. But the general concept should be clear - the short end would eliminate the volatility, unfairness and flash-crashes created by submillisecond trading. The encouragement to the longer end would get everyone to think longer-term. The 0% for decade+ holdings would prevent a lot of silliness around inheritance (e.g., you inherit a few shares from your grandfather, and have no records or reasonable way to figure the cost basis, but are required to assert one).
Of course, I doubt it would happen because it isn't in the short-term interest of the bankers.
