100% estate tax and 0% personal income tax

Pros:

• Personal development guaranteed. There is no limit, with no personal income tax.
• A flat society with less social hierarchy. All personal wealth is recycled when people die, with 100% estate tax. You may keep a few photos, a whole lot of memories, but no wealth, from the last generation. Everyone has a fresh start, brand new, with the same opportunity. No one gets lazy because of the money from parents. Children may get knowledge from parents, not wealth.
• Hopefully the wealth from the last generation covers all the expense for the next generation before their legal age. Food, shelter, education, and medical services. Every kid gets it free. In theory, the estate tax should be able to cover the expense, because basically the wealth is just passed down from one generation to the next.
• Poverty is no longer an issue, as everyone gets the same opportunity when they come of age. You can be lazy, and you can be diligent. It is totally up to the person who decides what kind of life he wants. There is a common misunderstanding as of income tax and personal development.
• Inequality eliminated within one generation, with 100% estate tax. Even if there is inequality in any way, it does not get passed down to the next generation.
• Works well with immigration policy. Everyone works for his own pension, and no one else gets a cut of it.

Cons:

• No known successful examples. Good news is, when you do it, you are number one.
• May conflict with vested interests. There may not be easy settlement.

All human beings are born free and equal in dignity and rights. But it does not mean we should levy personal income tax and make people have the same income. It is better the way when people have the same start, not the same result. People are different. Pursuing the same result is not necessary, and not possible.

People may choose to give wealth to children to avoid estate tax. Though, it could be easily fixed.

Vested interests are the impediment to social development. Debt or poverty is the result from vested interests. If we want to make a better world, we need to unite against vested interests.
