Consolidation over the last 30 years is the fault of folks here on HN. Information technology moves the equilibrium point between economies of scale and diseconomies of scale. It enables huge companies to operate efficiently. That enables them to leverage their scale to deliver better services and cheaper prices.
Consider Amazon. Everyone loves to hate on Amazon, but they’re doing it while adding stuff to the delivery they already have coming tomorrow. Why can Amazon ship me stuff overnight, whereas it used to take a week back in the 1990s? It’s not the internet per se. You could call in or fax orders back in the day—it still took a week. And delivery is being done using the same planes and trucks we have been using for decades. Amazon happened because technology enabled it to completely restructure the entire warehousing and delivery vertical, rendering a huge swath of the economy obsolete.
That’s happening all over the place. Most of these mom and pop businesses suck. They have shitty service, high prices, limited selection, etc. The big companies are better and IT enables them to scale in ways that were impossible before.
