It’s dishonest to hand wave it away while pretending that because there are government controls for construction and financing that it would go even better if it was more government or “more hybridized”. With no source, just opinion.
No one that has ever had to switch blue to red to green in toyko just cash, buying a new ticket at each stop only to go a couple miles, has ever forgotten how privatized Japans railways are.
I expected to see comments about how good it is, how most people love it, how it’s highly privatized, and of course about how to make it better with more government.
