I would imagine such aggressive measures (i.e. forcing of anything) would occur first in a certain other countries before it happens in the West - if it ever does. I would also not be surprised if the West would implicitly choose to implode first before sacrificing an iota of "freedom and individuality".
Outside the West, I also would not be surprised if some countries/cultures would implicitly choose to implode before sacrificing their homogeneity.
(If more aggressive payments by other countries are any indication, this will have approximately zero effect on people's decisions.)
