Why is Apple making me pay for all my old apps again?

In the past 4 or 5 years, I have paid $100's of dollars for apps (Your welcome, cheap *** holes… I mean Apple). Some of them I keep and some I delete. When I look at the app store and want to download a game/app I already purchased, it says the price instead of it instead of just "Install". For example, I may have downloaded the game last year, lets just say Infinity Blade (it was like $5.99 at the time) and now I want it again. I'm not paying Apple two times for the same app. What should I do?

I have an iPhone 4S running iOS 6.0.1

P.S.
A while ago I redownloaded Zombieville USA after I paid for it a year or two ago. I didn't think it would charge me again for it, but it did. I contacted Apple and they said they would credit the dollar back into my account ($1 isn't a big deal, but still).It's over 2 months and I still didn't get that money.

Added (1). 1. I don't need a job.
2.It's not being a 'Jew'. I'm not paying Apple another $200ish to get my stupid apps back… It's more about the point rather than cash. Money isn't a problem.

Added (2). I tried many times before I posted this.

How do get someone to stop using my twitter account?

How to navigate the new version of itunes?

Just recently got my girlfriend the new ipod touch 5th gen. I have the iphone 4 and have not updated itunes and when I did it on her computer, realized it was different…

The main thing I'm very confused and upset about is that it seems that you cannt drag and drop songs into itunes anymore? Can you? If not, how do you get your music on there besides going into file, clicking add files to library and doing them all individually instead of by albums or by folders? I'm trying to keep this all simple for her but it is so confusing using this new version myself…

How to delete Facebook for iPhone post off of public facebook profile?

I was tightening my Facebook security against unwanted public visitors and I noticed there's a post that states I've accessed my Facebook account from an iPhone device. This is true, but I do NOT want it there on my public profile! It is not on my timeline when I check, it is only visible to the public and I have no idea how to completely remove it. Also! I have tried to hide the date of my account creation by clicking the "hide from timeline" button but it won't remove itself off my timeline as well as stop random people from messaging me!

How to unlock an AT&T iPhone 4 without AT&T sim card?

I recently bought an iPhone 4 with AT&T from Ebay. I had trouble unlocking it with AT&T and decided to buy an unlock from Ebay. However, that didn't work either. A friend told me that I may have to activate a prepaid card with AT&T and unlock it from there. Both Apple and AT&T said there's nothing wrong with the phone but it's just locked on AT&T's network. If I put an AT&T sim card in the phone and try to unlock it that way, will it work?

Also, when connecting it to iTunes, it's able to be identified but it says that it can't be activates at the time and to contact customer support. When turning on the phone it doesn't activate either. I assume that's because the seller factory reset it and I don't have an AT&T sim card to activate it with.

Any suggestions or anything? ANYTHING will help. I just need to make sure the phone itself isn't broken or anything.
