There’s nothing ‘mysterious’ - but I am arguing that your attempt to try and compare Mamdani’s proposals for NYC with the systems in place in entire other nations is a flawed comparison intended to discredit Mamdani without actually debating or analyzing his policies. Every situation (country is unique) - whether socialist or capitalist, the success or failure of any policy depends upon a wide range of variables - institutional strength, corruption, poor implementation, poor enforcement or just a poorly designed plan. So arguing that X country has a ‘socialist label’ and did not implement Y policies successfully does not necessarily have any bearing on whether similar policies would fail or succeed elsewhere, in a different environment.
So, if you’re done deflecting, let me know if you actually want to discuss Mamdanis Policy proposals for NYC.
