1. It isn't JEWS in general that you have a problem with, just your bosses, so to say Jews are cheap is wrong and discriminating.
2. You work for them to get a job done. It is their right to save money and by law they only have to offer minimum wage. If they feel 20 cents is a decent raise, that too is their right. It is also their right to open more stores to grow their business. And just because they opened more stores doesn't mean they are rolling in the money and how do you know they don't contribute to charity(s)?
3. If you owned a business, would you throw all the money at every person who griped about pay? Maybe you gave your workers a .50 cent raise. Next year they expect more. Then the next year they expect a .75 cent raise. Depending on how many personnel they have, their expenses, and their own salaries, it may not be feasible to offer every employee more than a 20 cent raise.
Honestly, I would rather use something until it can no longer be used or fixed than to blow out money on all brand new items right away. Get the use out of it.
Face the facts, not every business owner thinks about the little man and not every little man appreciates the business owner.
You can always hit the unemployment line and search for a new job. There will be someone there in that same line who will be all too happy to take your place.
