"On the other hand, if the share price has increased because the company is more valuable, then the government shares have also increased"
These two statements are completely contradictory.
>>>>>>> "The current problem is that, in theory, it is worth it for a company to pay accountants and lawyers $99M to reduce the tax bill $100M. "
This is not remotely true.
First, complicated taxation is the decision of the government, not the industry.
Second, Amazon's low tax burden is not a function of $99M in lawyers, it's a function of the fact they don't make any profits.
"The whole problem is that the public is not getting a "stake" of the income stream."
This is again, is not true. The public is absolutely getting a stake of Amazon's income stream. The problem (as some see it) is that Amazon has very little income.
Amazon, as it stands today is like a non-profit NGO. They make very little money. Their surpluses are given away to some other part of the value chain: suppliers, customers or employees.
This is specifically an issue of international repatriation and has little to do with anything else really - and your OP doesn't really aim at that.
Amazon is a poor example because they're not in the business of fancy IP arbitrage: this is what Apple, Google and FB do. Less so Amazon.
But the problem is that US taxation with respect to repatriation is messed up.
1) US corporate tax is very high - the highest in the developed world. 2) US expects companies to pay 'full tax' when repatriated money, even already taxed money. Every other country just expects a 2-5% repatriation tax.
The US tax system is not designed for globalism.
What the US and the world need to do is find a new harmony which will entail:
1) Lower US corporate taxes 2) Close all the special loopholes 3) Get rid of double-taxation on remuneration 3) Especially for digital and IP - taxes need to be paid in the local state where business is done. FB is selling ads and consumers are consuming them in France, then a good chunk of taxes need to go there. Same for Google. The US is going to have to eat this or face punitive war forever from EU and other nations.
If Apple has no reason to recognize profits in the US, I assume Matsushita has less reason to, so it doesn't really matter if foreign companies don't pay out to the US. If anything, it makes it more useful for the US government to prefer to give business to US companies.
I'd love to see how one would "close all the special loopholes" and force the companies to "pay taxes in the local state where business is done". This is exactly the problem. You reacted to the "ideology" of having a government share of the company, but your solution would require a much more invasive bureaucracy to accomplish the goal.
On the other hand, if the share price has increased because the company is more valuable, then the government shares have also increased. If there is, in the future, a 1% quarterly dividend, then the government will partake in a 1% dividend on its higher-valued shares as well. The federal government doesn't need to pull in all the money now. It has a large ability to borrow where it needs and corporate taxes make only a fraction of tax revenue.
The current problem is that, in theory, it is worth it for a company to pay accountants and lawyers $99M to reduce the tax bill $100M. Economists call that waste. I'm pretty sure just about everyone else thinks it's problematic to create industries that get rich off of nothing but moving money around to avoid paying taxes.
The whole problem is that the public is not getting a "stake" of the income stream. The law says we do but in practice we do not because the money is being very cleverly moved around.
Arguing that there should be no corporate income tax is a different thing. This discussion is about how to collect such a tax.
