C Юлей Вишневецкой меня познакомила в Нью-Йорке ваша подруга Катечка. Они большие друзья.
Юля показалась мне очень симпатичным человеком.

Милтона Фридмана я не читала, только статьи о нем, в основном Наоми Кляйн, которая его совсем не любит..

Однако, Фридман действительно писал о негативном налоге:

Specific models

Milton Friedman proposed a model in which a specified proportion of unused deductions or allowances would be refunded to the taxpayer. If, for a family of four the amount of allowances came out to $10,000, and the subsidy rate was 50% (the rate recommended by Friedman), and the family earned $6,000, the family would receive $2,000, because it left $4,000 of allowances unused, and therefore qualifies for $2,000, half that amount. Friedman feared that subsidy rates as high as those would lessen the incentive to obtain employment. He also warned that the negative income tax, as an addition to the "ragbag" of welfare and assistance programs, would only worsen the problem of bureaucracy and waste. Instead, he argued, the negative income tax should immediately replace all other welfare and assistance programs on the way to a completely laissez-faire society where all welfare is privately administered. The negative income tax has come up in one form or another in Congress, but Friedman opposed it because it came packaged with other undesirable elements antithetical to the efficacy of the negative income tax. Milton preferred to have no income tax at all, but said he did not think it was politically feasible at that time to eliminate it, so he suggested this as a less harmful income tax scheme.[2][3]
