People do know how they will be affected, because they know what parts of Obamacare they don't like. They know that the premiums for Obamacare are impossible to pay, especially if you have a family. They know that things will go back to the way they were before, and that is better than now.
People don't know or care about how they and others will be affected. They believe what they have been told which is that they are carrying the useless baggage of america (that would be better off dead if they can't take care of themselves without their help, in their opinion) and that without that extra weight holding them down they'll have a much better life.
Just like welfare and food stamps, which they consider as stealing the very food from their mouths for lazy good for nothing slackers (not realizing that the very VAST majority of these are the working poor (sometimes working nearly 2 full time jobs) who would starve without the assistance even while working.
We have demonized the poor that they can't succeed because they don't try hard enough, or are bad people even as they work hard just trying to survive. We keep hearing about crime from the poor but do people realize that the amount of wage theft is TEN TIMES the TOTAL cost of regular theft?!
The value of work done by a middle class worker is based on the value of work for the lower class. If the lower class is reduced to dying on the side of the road (as long as the rate is below reproduction) then the middle class worker will be working 2 jobs and barely feeding themselves. Even then they will still blame the poor for their situation with how much it costs them in taxes to drag their dead bodies off the side of the road to the incinerator (or compost pile as the case may be).
Many people that have insurance as part of the Afforable Care Act (ACA) don't even realize it. A good example of this is when a person has certain coverages that weren't there before, or when a person is able to afford health care insurance even though they have a pre-existing condition. Children being able to stay on their parents' policies until the age of 26 is another great example. If people truly realized the advantages of the ACA they wouldn't be so quick to want it gone.
The Affordable Care Act is confusing and the repeal process will further the confusion for many. People just want low cost health care and easy access to medical care. The impact of the repeal may not be understood for years to come. The lack of leadership and communication will make the next steps difficult for all.
Most do not know how repealing the Affordable Care Act will affect them. There will be many unforeseen consequences for getting rid of the Affordable Care Act. Even though the healthcare law has been fraught with controversy, undoing the law may be just as painful for some. It might be better to just reform the law.
