dollar signs aren't "just digits" when you're struggling to feed a family of 4 or trying to make ends meet because you have exhorbitant medical bills.
You weren't comprehending...
Why are there even dollar signs on the medical bill in the first place?
If the dollar system was completely eliminated, all forms of currency was done in some form of "crediting", where you go to work, you get a specific form of credit given for the time spent working. Each and every person gets the same amount of credits, one no higher than the other. Enough to get what they want in life. What's the need to distinguish in this in the format of money?
Money is just used to socially rank people apart from another, for what reason I have no utter sense of understanding why else aside from making certain people stand out from others.
Think back to the 1500's if you can. Maybe the 1300's. Before coined currency was declared as a norm. People just worked on farms, did labor, got healthcare that was done for FREE out of GOODWILL that were free of monetary grasps (although not technologically advanced), without having to rely on cash.
Now do you see what my point is? Somewhere along the line, someone thought it would be cool to add another factor called "HOW MUCH MONEY DO YOU HAVE!?" and it messed up everyone for the future. Not so much for those that are getting along with minimal issues, but that's just the minority. The majority is still struggling to work with this system today.
USA doesn't have free healthcare
Canada's economy isn't as booming as the US's
Europe has to deal with whatever struggling problems they have
Asia is recovering from their archaic forms of government to adapt to the new capitalism (yet continue this growth again)
The fix isn't easy, but like I've said tirelessly over and over - people need to get educated over this first, that's the biggest factor that's involved at this point in time. Everyone is just blindly following the system and caring about other means of problems aside from the real problem itself.
