The Feds just busted 27 "medical" growers in Michigan for growing to make a profit. If they won't let the growers make a legal profit how the hell are they going to tax the shit?
Well, as I said, we see that in CA also. They are only, as you say, "medical" growers. Quotes.
But, it is for profit, and I bet it goes out of State. So, in govt, remember you are not an individual. There are big programs at work all the time, in secret.
One of these is the wind down on the Drug War on Pot. Very complicated as we ship tons of Ben Franklins into the S.Am economies.
We don't want riots in Colombia and in the Michocan, etc. That is a separate but equal problem.
They want to tax Billions of Dollars in US illegal economy. Not easy and not in my job description to cypher.
But, to do that, States that are far from Compassion Minded and are still strict on ganja have to be protected from the illegal interstate commerce. And the ganga State needs protection from un-reported profit.
I think of States as Mob Families. We all pay tribute to the 50 family org, called the Feds. So, you think it is complicated for the 5 families on Manhattan or the Chicago Mob, this is 50 Families and each family has 100s of Crews in the form of Counties.
It is a Mafia in fact. Organized crime in bed with illegal organized crime. Thus it is ever so. And it is a GOOD THING. It is only alternative to warlord.
