do you know who said tying the basic income to vaccination and etc?
It is already the law in Denmark. You can have your UBI/unemployment/COVID-19 benefits suspended if you refuse vaccination and/or testing.

It is one of the countries with the most widely implemented measures akin to UBI, and quite a few politicians on this side of the ocean have already voiced strong support for modelling any future UBI programs on what Denmark and other Scandinavian countries have implemented. I doubt it will fly, but considering the current environment is quite purposefully engineered to destroy everything that makes us human I find it really hard to believe the powers that be will simply start handing out monthly checks with no strings attached. If they cared so much about us then why engineer everything (for almost a century) so pathologically and quite openly with complete disregard for health/dignity/life/freedom??
