(Granted, I don't understand basically anything about tax law, so maybe this is already a well-defined problem with a well-defined solution.)
As a novice, this feels like an approach that punishes the well-off, who may not expend the resources to structure all assets/liabilities this way, at the expense of the super-well-off who will simply pay multiple other people to re-organize their own financials.
There's no such thing as a negative profit. That's called a loss.
Taxing the income real people get paid from the corporation would be the logical, and much simpler system.
* You can of course also make a decent argument against this :)
The people that you are talking about are effectively lobbyists - policy entrepreneurs is the phrase, who appear in the media advocating for policies that benefit their clients.
All it is is that the legal system decided it would make sense to apply the same laws in some areas to both companies and humans, rather than design completely separate frameworks for each case.
In HN terms: This is code reuse/refactoring.
Humans, on the other hand, all work mostly the same.
Different amounts of value are added at different stages of the product pipeline. These different amounts of value are reflected in different profit margins. Forcing uniformity here via the tax code would be massively distortionary.
Also LLCs operate this way already with pass-through taxes which is why they're used so often in real-estate. It allows for limiting liability and splitting ownership and management without adding a whole new tax basis.
That way you don't have to mess with income reporting, deductions, loopholes, etc. Just pay a % of each transaction directly to the government. Credit card companies and banks could even automate this so it's completely transparent.
Maybe leave INCREASE CAPITAL GAINS in all caps. Or, CAPTURE THE SAME MONEY AS DIVIDEND INCOME OR CAPITAL GAINS.
Perhaps: IT IS THE SAME MONEY CAPTURED LESS CONFUSINGLY AND LESS PRONE TO CHEATING
Taxes are not a moral issue nor do they have a victim. The proposal isn't to eliminate them entirely, only to remove corporate income tax and make it up in other changes for a net win for the economy, and it's perfectly reasonable to discuss.
