This is the outcome of Capitalism . Even the new Open Access Operators are no guarantee of sustainable salvation. As Capitalism in a free market will always seek to acquire and merge. Or out compete and destroy competition.
This isn't capitalism, it's more cronyism where the government takes on all the risk but outsources any profit to private companies
If it were capitalism, the full system would've collapsed over covid where there weren't enough passengers. If it were socialism, it'd probably be largely the same given the number of lines that do lose money, but at least the profitable ones like the London-Birmingham/Manchester routes would be adding money to the government instead of private companies
Cronyism is a symptom of any (not even the) class system, not capitalism. Those with power (ie those charged with administration/lawmaking under communism, those in power/with sufficient capital under capitalism) abuse their power to give more power to their friends and those like them. The only cure is openness and transparency in book-keeping and policy-making, but that's not an economic ideology but a political one.
