First, since I am pretty sure your "estate" is not worth more than 5.5 million, why care about those who do? They sure as hell don't care about you and your family.
Second, lets say by sheer luck (not skill) you estate happens to be one of the 0.2% of the estates that pay any tax, can you honestly say they your family can "barely survive" on 5+ million?!? You raised a foolish family. Lets go thru a typical scenario, you die at 75, you wife gets it all, tax free, she is taken care of. She dies later at age 76, that puts your kids in the 40's or 50's. Are you saying your lazy kids have been waiting around 40 - 50 years doing nothing but waiting till you die? You must be a great parent! No, if you have 5+ million in you estate, you send your kids to the greatest schools, and thru you business contacts with your gulf buddies at the Trump Golf Course you set them up in executive positions. Your family should already have their own lives and fortune.
The Estate Tax was set up by our Founding Fathers to prevent a plutocracy like they escaped from England. Many can argue we have it now. Estate taxes help prevent families that own empires (yes, I know they just raised the cap and not eliminated it, yet) like Walmart, go from generation to generation, doubling and tripling their wealth till the point comes that EVERY business, house, plot of land is owed by one of a couple dozen families. So much of for the American Dream, unless you are lucky enough to be born into one of those families.
Now here are the facts and stats about the current estate tax, before the proposed changes. This you won't see on Fox News or hear from Rush Windbag.
ONLY 0.1% to 0.2% of the estates are taxed.
If a family is "blessed" enough to be that wealthy, they average a payout of less then 17% of their total estate, due to lots of current loopholes.
Of the estates that were taxed, less then 1% were small businesses or family farms, and with proper planning most of the tax could be avoided.
For the larger estates, most of it is on "Unrealized Capital Gains" which is the capital gains tax they would have had to pay anyway if somebody sold off their estate just before dying. Mostly, Estate tax just collects the tax after they died. on stuff they should have paid before they died.
Since you chose the misnomer of "death tax", I know where you get your misinformation from, try googling up the truth for once.
