The way you fix the existing system, is by not trying to change it. You replace it instead. You build new, lighter, more nimble approaches to old problems, rather than trying to convince existing power structures to change. That's where any gains will come from by big tech entering the fray, if there end up being any.

Trying to change something like the hyper regulated, hyper stagnant, special-interest dominated US healthcare system, is a folly of an idea. You kill it instead by routing around it with new solutions wherever possible.

Simple example: the rapidly growing market for direct primary care subscription services [1]. Pair that up with guaranteed catastrophic coverage for all by the US Govt or state governments, and the US healthcare system as we know it is dead due to a simple route around that would dramatically lower costs. It's far easier to implode a failed bureacracy by replacing it in that manner, than by trying to change the existing bureacracy. You see that in everything from old media (which held a cartel stranglehold on broadcast access, the Internet routed around them), to the taxi medallion cartels (which Uber & Lyft murdered by routing around them instead of trying to convince them to change).
