It’s also worth noting that the transition to the “salary cap” would likely cause a recession, or even a depression.
To illustrate, in the town in which I live, perhaps 25% of the homes were purchased for over $600,000. The mortgage payment, taxes, and insurance on such a home would make it difficult or impossible to keep up with the payments on only $100,000 of income. Thus, a lot of mortgages would be thrown into foreclosure if a salary cap were implemented.
Now, you might think, who cares about the rich - let them move somewhere cheaper, but consider that a big wave of foreclosures would threaten the solvency of many financial institutions.
Consider also that in the presence of a “salary cap,” many people would do their own yard-work, cleaning, and child-care instead of hiring others. This may sound like a nice idea, but it would put many many landscapers, maids, and nannies out of work. Many of these people, in turn, would default on THEIR obligations, causing further economic distress.
You can bet that a “salary cap” would have many of these unintended consequences and cause a LOT of economic dislocation.
Personally, I think we should leave “bad enough” alone.
These grand schemes to bring about utopia invariable have serious unintentional negative effects, IMHO.
That said, I must say that I have lived in the NYC area, which is very wealthy and has tremendous disparity in wealth; and New Hampshire which is much more egalitarian (but much poorer). I must say that New Hampshire has a lot to be said for it – in many ways, it’s a much nicer place to live. I’m just skeptical that we could turn NYC into NH through legilative fiat.
