Most of this article is lucid. I’d quibble about whether there is one laffer curve to be looked at to maximize government revenues. I suspect, you could have differnt curves for different segments of the population, and that the peak of the curve changes with time and geography and local economy. However…

… this ‘fix’ brought me some pause:

You need to start with closing all the loopholes and enforcing the current laws

We have had governments reigning for over 6000 years. In fact, during that time, governments have gained strength to heights unimaginable just 200 years ago. Nation-states themselves are a relatively new concept, and governments have never been more powerful. Loopholes are never fixed, and they always benefit the rich or evil.

Your statement is exactly the same as saying “we must all be on the same team to solve the problem”. When that team contains more than a couple of hundred people, you are not all on the same team anymore. Fundamentally this is why controlled economies will never, ever, work. A million people will never be on the same team, but they have a better chance than 10 million people. And 10 million have a far better chance than 100 million. The idea of closing loopholes to fix a perceived revenue problem is almost nonsensical.

I would suggest that the entire premise, that “government should maximize its revenue” is the very heart of the problem. Governance should be a service, something can choose to participate in and which ones to participate in, or not at all. Watch how the prices for government services all of a sudden drop. Watch how the rich all of a sudden need the poor and middle class rather than their cronies in government.
