The upcoming US presidential election is pivotal for both American democracy and the global economy. Voters must choose between Kamala Harris, who aims to continue Joe Biden's policies on competition, environment, and inequality, and Donald Trump, whose agenda favors coal, oil, and the wealthy, potentially weakening the economy. Trump's past failures, such as his mishandling of the Covid-19 pandemic and harmful economic policies like high tariffs and tax cuts for the rich, highlight the risks of his leadership. His approach could lead to higher inflation, increased deficits, and reduced investment in science and education, undermining long-term economic success. Harris, on the other hand, is seen as a pragmatic leader who would use science-based decisions to navigate future economic challenges.
