I'm not British so I probably shouldn't get involved in British politics.
I think Britain needs the following reforms :
1. Nationalize all water companies.
2. Increase taxes on soda, sugar. Use the money to pay nurses and doctors better
3. Cancel Microsoft Windows contracts and switch to Linux. Cancel Microsoft Office contracts and switch to LibreOffice. Open Source can save the UK Government billions of pounds and improve national sovereignty.
4. Cap immigration at 2% a year. It's very clear to me that immigration in recent decades has been far too high. It has undermined the labor market, the housing market, and it may undermine national cohesion.
5. Reform the UK campaign finance system. Why are foreigners allowed to wire money to UK political parties? Why is there no cap on donations? Britain has the most corrupt campaign finance system after the United States. Being better than the US is the same as having no standards at all.
6. Ban MPs from having second-jobs. It's totally absurd. Many of them work as "consultants" or "lawyers" for big corporations. Many European countries banned these shady practices, but Britain somehow can't get itself to do it.
7. Change the voting system to Proportional Representation. First-Past-The-Post creates disillusionment and anger. If nothing is done, FPTP may give Nigel Farage an absolute majority with only 30% of the votes.
8. Reform the House of Lords. Currently, it's a joke. The overwhelming majority are from London and Southern England. They have lifetime job security. Several of them get paid just to show up, they play cards with friends while drinking tea. They vote for insecurity for everyone, except for themselves? Transform it into a House of Nations. With 200 people from England, Scotland, Wales and Northern Ireland. No centralized political appointments. They will be chosen by Mayors and Local Councillors.
9. Increase tax on private jets fuel. France did it . The low rate they pay is a scandal considering climate change and inequality. There is absolutely no reason why Britain can't do it.
10. Ban foreign newspaper ownership. It shocks me that a foreigner (Rupert Murdoch) is allowed to own many newspapers (The Sun, The Sunday Times, The Times). He directly told John Major to change UK Foreign Policy. Why is nothing done about this? Because Murdoch is a white Australian? I feel that if a Chinese or Turk told the Prime Minister what to do, people would scream "foreign interference". Foreign ownership of any British newspaper should be capped at 40%.
I respect Jeremy Corbyn and I hope he can get these 10 things done.
My main worry about him is foreign policy. He once called Hamas and Hezbollah "my friends" (1). He first refused to believe Russia ordered a chemical attack in Britain (2). He refused to send weapons to Ukraine after Putin invaded (3).
Too often, he just assumes that because the West has done evil things, the anti-Western forces are the good guys.
