The "Robber Barons" of today are the ones who do NOT want to REMOVE the Estate Tax.....because they have so many millions they protect their money in Foundations (and hire their friends and relatives) and, they've ALREADY GOT THEIRS....i.e. Wm. Gates, Sr....Warren Buffet.
OR....they buy out the littler guys when they're faced with Estate Taxes which would destroy their businesses....i.e. Warren Buffet....
