@miawgogo imagine if microsoft blew itself up entirely. there would be a lot of market openings all of the sudden. software that can't exist because microsoft has something that fills the space, and it may not be good, but its enough to suffocate making anything else.

that was america in the early days. power had not been fully consolidated (cf. the charts showing the 19XXs had hundreds of businesses, but the 20XXs they are all owned by the same six firms)

america wasn't 'great' it was a green field.
