From 2012 to 2016 I taught entrepreneurship, investments and history at Riga Business School and also taught 2-5 day entrepreneurship courses on Erasmus exchanges in business schools in Stuttgart (3 times), Valencia, Katowice, Cluj-Napoca, Romania (twice) and the Freie Universitat, Berlin. So you're assumption is as wrong as wrong can get. My Stuttgarter colleague from the Hochschule der Medien was as enthusiastic, hard-working and generous a colleague as one could ask for. Same for the Romanian colleague who invited me twice to FSEGA, Cluj. And the students were all first rate. I have lots of videos of the FSEGA students getting their classmates to play the startup simulation game I prototype with a Riga game designer.

10-12 years after I taught them, I still play basketball with several of my former students. One brought me the Printify startup investment before the founders and my student went to the 500 Startups accelerator in San Francisco in the autumn of 2016. I, my brother and another angel investor invested in 2017 at a valuation of $5m. It's now a unicorn. https://techcrunch.com/2024/11/05/printful-and-printify-ink-a-merger-deal/

I know from fortunate experience that there are returns on investment that no online course can yield.
