Always looking to be a blessing ;)
I fully and wholeheartedly support this.
I do know tho, that they would just import staff from other countries to do infrastructure work.
Do you think some German/ Spanish/ French/ Venezualan/Cuban/African/etc etc builders would give a flying fig about ruining America.
Some might, because their own countries would also be undergoing the 15-minute bollux, but a lot wouldn't care. They'd do the job more likely in another country than in their own.
This is such a good idea though, that really, it should be a worldwide movement. If all blue collar workers in all countries refused, then NWO is stuffed.
