How to Tackle Human Rights Issues at Work?

I've been working for a well known retail book store for over a year now, and it's been a nightmare from the first day. I come from a generation who had common sense, something lacking in todays society. The customer is always right, but as long as the rules were being followed and not when a hissy fit gets your way, and keeping employees happy and feeling proud to be a part of the company they're working for. In todays world, it's all about the number at the end of the day, and grading the employees on their performance on a daily basis, as if still in school. Even hiring "secret shoppers" to go around to different stores to order something a certain way so they can grade the person on if they asked the proper 3,4, or more questions, and making suggestions on the larger sized drinks and food items, and doing this in a 2 minute time frame. As a customer, prior to my working for the store, I was always annoyed at this every time I went to enjoy the one or two things I would order, not to mention how messy the food items were when given to me, or that the drink I ordered was made wrong. Why? Because they are so into being the fastest one at the job, and making that 2 minute mark, that they would barely pay attention to what was being ordered, and ending up doing what they thought they heard. Then getting an attitude from them for trying to exchange it for not being made properly. The biggest thing I noticed, as a customer, was how ridiculous the person looked when racing around like that especially when I happened to be the only one in line.
I now understand why they race around like they did, and now it makes me incredably upset because none of this that is going on with the rules make any sense! All my days as an employee in the retail world was about the way you handled the job and how well you did this was rewarded by raises, more hours, tips from customers, being moved up to a better paying position, regardless of how long you've worked for the company. Being proud over the job you do was common, not much of that going on today. It goes unoticed when you give 100% into your job now a days, and even when customers are contstantly letting you know how they only come to "this store" because they like dealing with you because of how well you take care of them, and how friendly you always are. I'm hearing things like, "I'll walk out without ordering anything when I don't see you." or " When I see so and so working, I will just leave because of the way so and so is always getting it wrong. They move around too quickly and never pay attention. " However, employees get rewarded for being so fast which amazes me because of how much waste is made when having to do something over again. I do not understand how it all works in the long run! What happened to doing it right the first time, within a reasonable amount of time, service with a smile, and not treating the customer as if they can't think on their own? What about traing the employees in the first place, so their are fewer mistakes made, not as many complaints over how many questions are asked because an employee can learn who to ask and who may not need any suggestions made to them, and so much, much more. We have managers that play favorites and ones that think they are going by the book when they don't even understand the book themselves, and who play god with your lives. Now it's all about living for your job. Your life is your job, but you don't get paid for it. The hourly wage is a joke, and 20 hours a week is all they can do, yet trying to make your life work is not possible anymore because they don't believe in having the same schedule for you every week or even allowing people work the hours that best suit them, unless your a "favorite" of the one who does the schedule. I was even asked, "What will you do for me, it's a give and take situation?" Are you kidding me??? I do more than I should and have enough passion for 2 people and I'm told to take it easy, yet when I take it easy, I get punished by taking hours away from my next schedule, and you also get punished if you call out sick one day, yet are told that they understand when someone is sick because that can't be helped.
So, as I had asked in the beggining, what is going on with the way corporations have taken over and how they are ruining the years of our history as Americans have done things before this new way has become the norm? How do you think this will all turn out after many more years of this?
All I've mentioned was just scratching the surface to whats going on in the stores we shop in.
