How much was a new car back then? What was the min wage? What your not taking into account is that it`s not so much prices have gone up as money is worth less than back then and it takes more of it to buy anything now days.It`s called inflation.That 50 an 1/8 oz won`t buy more apples than when it was 25 an 1/8 back then. so if prices go down much it would be a loss of income from what people would have got years ago. If that happends less people would grow and sell marijuana and it would get dry until the prices went back up.That`s where supply and demand come into it. More people growing the less the price is until the market gets flooded and then people can`t make money.Then they quit growing and the price goes up because people will pay more because it becomes harder to get.
Don't forget one thing....if this passes...10's of thousands of people will 'grow a plant'. The occasional smokers, the older peeps from the 70's where everyone grew a few plants in their backyard. A lot of these people, since it will be legal, will grow again.
Less people growing? The only way I see someone stopping their commercial grow is if they start to lose money. Meanwhile you got thousands of other people growing their own.
Overgrow
