I don't think you'll like Israel. It's very much a socialist country. But, if you're even part Jewish, it's very easy to get a passport and you can't renounce your U.S. citizenship if you don't have another passport. For me, taxes are not the sole problem with the United States. High taxes and the insistence on taxing its citizens where ever they are is a symptom of tyranny and I'm allergic to tyranny. At one time, this country almost perfectly embodied everything that I believe in (which is pretty much everything in the constitution). Today, it embodies mostly everything I despise. Life, liberty and pursuit of happiness is limited to the political class which has used its law-making powers to turn us into serfs slowly enough that most people don't even realize they're becoming serfs. The very fact that I'm not free to work here and pay taxes voluntarily and I'll be hunted down where ever I am in the world by U.S. thugs euphemistically known as the IRS, makes me feel like escaping. When a country has to trap its citizens, what does that say about the country?
Every country except the United States and North Korea. Other countries tax based on residency. The U.S. taxes based on citizenship. Thus, if you don't live in France, France doesn't tax you. That's what I mean. If you're French, you can avoid the 47.5% top marginal tax rate by moving to Singapore where the top marginal tax rate is about 18%. I don't mind paying taxes. I mind being trapped.
That is not a "voluntary" tax. It is like two states that have an agreement not to tax the other's residents if they work in your state. You still will pay tax where you live. And I suspect this whole live in another country - everyone but USA and NK so you don't have to pay their tax is way oversimplified.
It's voluntary in the sense that you can choose where you reside. I don't know how much more complicated you think it is. If I were a German citizen, moved to Singapore and lived more than 6 months of the year there, I would not pay the German tax. Instead, I would pay the tax in Singapore. The United States will go after you even if you don't so much as set foot in the United States for 4 decades. Call it what you want, but it's a sad day when the U.S. government owns your ass no matter where you are.
