Might doesn’t make right, no, but what exactly do you think rule of law is when it doesn’t represent the will or the welfare of the people? The people you’re complaining about carried signs and disrupted traffic. The people who stopped them were armed and had the force of the law behind their actions.
The rich people won’t have any better coverage, either. I know someone who had his daughter flown to the Mayo Clinic for mono. Yes, her case was very bad, yes, they were Canadian, no, that’s not an option that is available to the majority of us, and no, being part of America won’t appreciably improve their options more than that.
