There is no point in building wealth or a family business other than to ensure your family will benefit from it when you're gone. Sure, childless young people with no perspective don't understand this mindset of intergenerational family businesses.
Community and society tax me for everything I do, eat or drink, all my life. Wealthier people already contribute more per capita than most other people, while getting the same benefits. What's the rationale for feeling obliged to contribute even more? Survivor's guilt?
This makes no sense. There is also no point in starting a (for profit) business except to make profit. Neither inheritance nor profit are eliminated by taxes - they are reduced.
For assets not taking advantage of the step up basis in New York (e.g. small business profits) the tax rate would be ~50% federal and state in the year earned, plus 56% federal and state when you pass. That's an overall rate of 78%... I'm not sure "reduced" is the right word here.
