A potential fix would be to allocate the taxable profits made by multinationals proportionally to the amount of sales they make in each country.

Say Google’s parent company Alphabet makes $100 billion in profits globally, and 50 percent of its sales in the United States (a relatively similar scenario to the first quarter of this year, in which that figure was 48 percent). In that case, $50 billion would be taxable in the United States, irrespective of where Google’s intangible assets are or where its workers are employed. A system similar to this already governs state corporate taxes in America.
