Those catching your derision are the ones whose labor fortunes have been built upon.  From those toiling in a Carnegie steel plant more than a century ago to those currently working at Walmart, there is commonality, in both cases those doing the laboring remained poor while Carnegie and the Waltons got obscenely rich.  

"Everyone should be expected to pay something. Nobody should be given a pass."  So you support the estate tax, right?  Because the heirs shouldn't be given a "free pass?"  

And while your question was meant as an insult, the poor pay everyday; they pay higher interest on debt, they have lower quality healthcare, they spend a much larger percentage of their income towards sales tax, they are priced out of home ownership, they die younger.

But by all means tell me about the hardship of the Walton heirs that will only inherit a meager $120 billion.
