The example of the former are dockers in many US ports (you usually can't easily build another port next to existing one), and of the latter, construction businesses in some US cities, like NYC.
In addition to that pressure, the largely pro-union and pro-labor EU could probably be easily enlisted to adopt a similar policy, thereby locking out offending companies both out of the US and EU markets.
Further, take a look at what happened to the ultra-secretive Swiss banks, which for hundreds of years have held the privacy of their clients sacred, even against the prying eyes of the IRS. The US exerted its influence, and now there's a lot more transparency in even the formerly-secret Swiss banking system. Many of the recent revelations regarding the tax-evading super-rich and what assets they have hidden where have been a result of such increased transparency in the global banking system.
US influence extends far, far past that. If the US decided to become pro-union and then hold the feet of other countries and companies to the fire were they to be anti-union or anti-labor, they could make a huge difference. It certainly won't happen in the current political climate, but it could be done.
Consider just two critical aspects of our society that require money to run smoothly and efficiently: modern medicine and industrial agriculture. Billions of people depend on them to survive, and the reason people participate in them as they do is mostly for money.
If you replace money with, say, barter, how many sheep or goats are you going to pay for a modern hospital or for a pharmaceutical factory, or the network of roads and airports needed to deliver food and other goods? How are you going to transport all those sheep and goats throughout our ever more interconnected world? At the very least, the infrastructure is just not there for us to switch to barter anywhere in the foreseable future.
Even if we could/did switch, all sorts of new power structures would likely arise and overthrow existing ones, and it's far from guaranteed that the transition will be bloodless. More likely, a lot of people would oppose it and it's not inconceivable that wars could be started over it -- especially as the change would probably not happen globally at once, but some countries would convert to barter first while others will still have money, leading to power imbalances, migration of money and the people who have it, massively influencing the economies, societies, and politics of the countries involved.
If the switch from money is not to barter, then to what? It's good to think about these things, and it's critical that our world change from the destructive course it's on now, but I for one don't see a way to extract money out of the equation without massive suffering.
My own slim hope rests on consciousness change, perhaps through education, increased communication, and maybe even psychedelics. The psychedelic renaissance has begun, and these substances are one of the most effective means of attaining radical changes in perspective and increasing creativity. Perhaps through them some solution that's not yet evident could arise, and if enough people change their mind maybe we could change our society towards a more positive and inclusive model.
The current circus show will return to some balanced "normality" once the media/social medias bullshit reinforcement mechanism namely the likes/upvotes/views/retweets/clicks/ratings is regulated. This mass overloading of people's minds with information they will never be fully trained to handle will break down soon enough. You can see that breakdown happening all over the place. People are still in denial that celebs like Obama and Trump were propped up by the same mechanism. Not dismantling that mechanism will keep propping up more and more bizarre and inept celebs with best pandering abilities in various power heirarchies not just politics. There are clowns in the army and judiciary who are playing the same game Trump and Obama play.
Removing/delaying/temporarily hiding the reinforcement of people superficial beliefs is the only way sanity returns.
I have a pet project along these lines but I’d like to hear other ideas: https://www.wired.com/2014/07/document-coin
