Brazil might actually get more investment from the US and UK. The US is likely to be much more focused on the Western Hemisphere and to lesser extent maybe the Far East too. They aren’t going to be investing as heavily into Europe without the world wars. The US especially won’t be as dominant in Europe economically as otl. Trade is going to be more mutual and less one sided by the two. Germany probably dominates mainland Europe economically while Britain has a tight grip on most global trade. Britain controls 1/3 of the world and has the world largest navy. Germany might be more advanced in industry and have better production but Britain has control over a large amount of the world’s raw resources. Britain and US could have a odd relationship when it comes to investing in Latin America or South America. Britain probably distance itself more from Europe then otl and starts focusing more overseas especially in places like Latin America. The question is how much would US and UK business and investors blur together in Latin America. A lot of British and New England capitalist often worked together and mixed.
The investiment of the kind that the US and the UK are going to do are basically setting up here factories to send the profit back to their home countries since Brazil remains without any kind of labour regulation without the world wars. At the end this can blow over and we have a left wing dictatorship in Brazil, or things proceed as they are and Brazil is turned into a american economical colony as OTL.
