There is an intrinsic fatal flaw of Democracy that will inevitably lead to its decline and this is being played out currently, although gradually. The wealth tax in California and the election of Madani in New York City are exemplary of this eventual collapse.
Simplistically, the electorate is divided into two groups. The makers, those that produce, grow the economy and pay taxes, and the takers, those that rely on government and receive more than they contribute. As the nanny government has grown, handouts have flourished and redistribution is the goal. The takers are growing as a constituency and as they electorally outnumber the makers, they will vote to enable the government to take evermore from the makers to give it to themselves. Essentially voting themselves a raise. The makers will gradually have to give up progressively more of what they earn, eventually squashing their motivation.
The ideal of one man one vote sounds equitable but in certain ways is a wholly unfair system to assign one vote to someone who works and contributes to society, and an equal vote to someone who lives off government redistributive handouts.
The founding fathers anticipated this eventuality which is the reason that land ownership was required in order to vote. Subsequent US governments objected to this prerequisite and expanded the right to vote to non land owners. This one move, however well intentioned, planted the seeds of the eventual destruction of the American experiment.
The raison d'etre of the progressive governments being elected is not so much the socialist ideal of government control of the means of production, but rather extreme redistribution. In the case of NYC, Mamdani was elected on the platform of affordability, a code word for raising taxes on the makers to give it to the takers. In the other case, California's wealth tax is not as subtle, as it is clearly designed to take/steal property from the makers to support the state government in its unlimited and unaccountable spending and redistribution schemes. These elections/propositions are demonstrations of takers voting to enable the legal stealing from the makers (in the form of ever increasing taxes) to give handouts to the takers in exchange for their vote.
The takers can essentially vote themselves a raise as they will never vote for a candidate that wants to cut the handouts they are receiving. Of course, the system will eventually implode as the maker class will wane as they have little incentive to produce and thus fail to provide the wealth to support the takers.
Furthermore, instead of investigating their systems for widespread fraud and abuse, it is much easier for the government to keep taking from the makers as they are an insignificant part of their constituency anyway.
From a demographic viewpoint the situation is both inevitable and quite depressing. There does not seem to be a solution to this eventual descent into socialism and extreme redistribution. People will try to escape by continuing to move to states where the process hasn't progressed to the extent as in California and New York. But it's only a matter of time until the federal government is affected by the same trends when socialism and extreme redistribution becomes the law of the land. At that point, the only remaining option is to escape the USA. Get prepared. There is a limited amount of time left. Look to move assets outside the USA!
