> Do you think there would be more or less innovation with more smaller firms?
Likely less, I do not think that private space exploration or self driving cars would be possible without the massive accumulation of capital enabled by tech giants.
Now let's look at the counterfactual, the US has massive tech giants and the majority innovation comes from or to the US. Other countries don't, other countries don't have nearly as much innovation bar a few exceptions.
And truthfully, I find people that are anti capitalism to be far more interesting. It's amazing that people can convince themselves that private ownership is wrong while living in the most prosperous time in history and also believing that stripping those better off of their wealth will somehow lead to a more prosperous society when every time it has been done it has lead to disaster.
