The USA has the presidential primary or caucus system, which will be held early next year. It's far more democratic than anything China has post-1949. As for Huawei, it's a trojan horse, which is why the firm has been banned from operating in so many countries.
The USA system of democracy has unfortunately become corrupted by so much dark money that it no longer works. Both parties answer to outside financial and corporate interests not the people. This is surely plain for all to see. Huawei has only been banned in western NATO aligned nations. The Snowden revelations (Vault 7), which led to the Guardian offices being visited by MI6 and staff forced to smash the hard drives in their offices, revealed that US intel agencies had "back doors" into Apple, Microsoft and all western Tech companies. The collaboration and spying by our intel agencies via all these means was exposed by the leaked files. It was massive and pervasive.
The reason for the Huawei ban is not because of Chinese spying, it is because our intel agencies would lose some of their own ability to surveil their own populace. Vault 7 revelations do prove this conclusively, Steve.
You should ask yourself, Steve, how come the media and government figures are apparently worried about supposed Chinese spying that is based on nothing more than suspicion and innuendo but ignore the hard unequivocal evidence that it is our own intel services spying on us. What have you read or what do you know about Vault 7?
