Estate tax

When ever the national debt increases like it has the past few years some politicians cry out that we are passing this, currently $30 trillion, onto out grandchildren. While this is true they fail to mention that the baby boomers, those people born between 1946 and 1964, will pass on $70 trillion to their heirs. The downside is that most of this will be in the top 20% which will add to the chasm between rich and poor. This is the argument for estate taxes.
