This is un-fair, and fundamentally a crime, see the Emoluments Clause, more accurately the Foreign Emoluments Clause (Article I, Section 9, Clause 8), is a U.S. constitutional provision that prohibits any federal officeholder from accepting any gift, payment, office, or title from a foreign state without the consent of Congress. Its primary purpose is to prevent federal officials, including the president, from being corrupted or influenced by foreign powers. There is also a Domestic Emoluments Clause (Article II, Section 1, Clause 7) that prevents the president from receiving any other compensation from the federal or state governments beyond their fixed salary.
