More specifically, other states will keep an eye on Ms Sawant's economic experiment to see if it works or not. And if it works then Ms Sawant will be a hero, other states justifiably considering implementing Ms Sawant's economic theories in their states.
But if it doesn't work, then the economic damage caused Ms Sawant's misguided vision will hopefully be contained mostly in Washington State, not messing things up significantly for the other states.
In fact, when Obama was an Illinois state senator, he had the 10th Amendment power to experiment with Obamacare within that state's borders. And if Illinois-run Obamacare had really turned out well for that state, then Obama would have had the bragging rights to argue for the states to ratify an amendment to the Constitution which would have granted Congress the specific power that it needed to establish federal Obamacare.
But if Illinois Obamacare had been a flop, then the states probably wouldn't have granted Congress the necessary power, via the Constitution, to implement federal Obamacare for the nation.
Otherwise, bearing in mind that the states want their economic experiments to succeed, socialist Justice Louis D. Brandeis had noted that the states were "Laboratories for Democracy."
The problem with Ms. Sawant's experiment, as freeper fhayek had pointed out, is that misguided socialists are infamous for repeatedly attempting the same failed economics experiments, expecting different results every time.
The tenth amendment does not give the states the power to violate the other parts of the Bill of Rights. Some things are not governments business at any level.
People should be prepared to revolt if they start stealing private property like this.
That is the second amendment
