A few simplified examples from off the top of my head:
pre ww2 most employers didn't provide insurance. during ww2 healthcare was offered as a perk of the job back in the day because wage freezes caused by world war 2 inflation concerns. you can say that because of hitler that it is the way it is now and now there is a huge political donation machinery to prevent single payer health care.(downsides being that if you are rich you can get really good healthcare for less than you'd pay into a single payer system and there are millions of jobs related to the bureaucracy of being in the middle of provider and patient)
china has very lax copyright/patent enforcement and as such places like shenzen's markets where you can find thousands of little electronic bits and pieces and clones are rampant with a very large maker movement. (of course there is a downside to this in that the capitalists don't get to benefit as much on whatever innovation was there originally)
regulatory capture on other industries are also from that lobbying.
