But, I've got a nagging voice in the back of my head saying "don't get greedy, cash out now!"

Greedy Landlords and they want free rent!

There is no reason they need to be in New York.Due to the high percentage of commissions generated by individual and institutional traders, such a tax could make brokerage firms less competitive with firms out of state.

It's not greedy unless they are being greedy.

First you will say "wow, there is a hell of a lot of down in the DOW" (yup, because traders make $ on, trading, not increasing, why there called traders and not growers).

I don't plan on stopping my investments with them, same with my other investments, I'm no day trader and in it for the long haul here, I treat it like my IRA, it goes in and I'll get it back way down the road. 

They tried the media--poor old folks being forced out by greedy heirs. 

No, Don't be a greedy landlord.

I got greedy, over confident, and was being "too nice." 

If they had greedy landlord and refused to return the deposit without clear reasons, they do not want to be take advantage by landlord and to protect themselves.
