Dear Sir:
While I find the amassing of large treasuries reprehensible in principle, I don't think government needs to be any bigger. I wish the tax policy would be written to better encourage gifts like these; perhaps a direct tax credit for massive money to institutions of learning and/or research that are operated without any influence or control from the giver. This would apply to gifts to any level from kindergarten onward including all subjects.

I also think that corporate taxes are always passed along to those who buy their products. And I do mean always. Corporate taxes are just price hikers.

Maybe a better strategy would be to tax all earnings equally, without regard to source or location, of all individuals doing business (including sales) in The United States of America. And to keep earnings at home by a policy of taxing at 90% any money leaving the country.  One tax rate: one minimum level of earnings before tax.
