The theory is based on the idea that it is easier to sell the drug to those who already took the vax, rather than to customers who will fight against taking it.
At this point in time, the drug pushers have figured out that easier profits can be made by targeting their [drug] product at consumers who have already bought into the sales pitch- fear, mandates, etc. rather than trying to sell to people who have refused their snake-oil for 8 months.
While this may be obvious to many of us, I suspect that the current narrative shift pushing for people to become multi-dosed will increase. And that push will be fueled by more rigged statistics.
Perhaps what is needed to end this cycle of madness is better (detailed) scrutiny of the statistics that are allegedly showing all of these "breakthrough" cases.
