Only a small fraction of those who would owe an inheritance tax are farmers, and the starting point of the inheritance tax begins at assets OVER ELEVEN MILLION DOLLARS. There is no requirement that people sell anything to pay the tax, anyway. If you have $11,000,000 in assets, borrowing against them is not going to present a major hardship, anyway.
I fail to understand why the 98% of the people of this country should be opposed to an inheritance tax thar will never affect them in the slightest.
