Why did Nikola Tesla die poor?

Nikola Tesla died poor primarily due to his inability to commercialize his inventions and secure financial backing. Despite his groundbreaking contributions to electricity and engineering, he often struggled with business acumen and was overshadowed by contemporaries like Thomas Edison and George Westinghouse. Tesla also invested heavily in his ideas and technologies, which left him financially vulnerable, and he faced numerous legal battles that drained his resources. Ultimately, his visionary work did not translate into the financial success he deserved during his lifetime.
