What problem was that?
When my daughter was just a baby, back in the mid 80's, she kept throwing her pacifier out of the stroller and then would holler like hell, and I couldn't give it back to her to shut her up because it was now dirty. So I tied a string on it and attached it to the stroller. It didn't stop her from throwing it, but it did keep it from hitting the ground and getting dirty or lost.
But the string didn't work well for bottles, and untying knots was a real hassle, and something that couldn't stretch restricted her from being able to drink her bottle while lying down in the stroller. A string only worked well while she was sitting up.
Elastic and snaps...it was perfect. Other mothers saw what I had done and wanted one for their kids' bottles, too. I made a bunch and kept them in my purse, individually sealed in little zip-lock bags. They cost me less than $1.00 to make, and I sold them for $2.00 each.
Then a good friend of mine suggested I get a patent for it and find a company to mass produce them and make mad amounts of money on royalties.
He put me in touch with a company that supposedly specialized in helping inventors get their products patented and bringing them to market.
Word of advice: Don't deal with these companies. They will do nothing to help you. It will cost you a lot of money and you will get nowhere.
After paying $400 for a rather poorly written "market study report", they managed to talk me into paying another $5000 and entering into a 5 year contract with them, promising to contact manufacturers and pitching my idea to them, and if a company was interested, they would get them to pay the cost of patenting it in my name, and I would get a royalty on every single copy of my invention that they manufactured, regardless of whether they actually sold any.
They convinced me that it was far cheaper to let them handle it, since they had offices all over the world and could set up meetings with company executives. They said my cost in air travel alone would exceed the $5000 if I tried to do it myself, nevermind hotels, paying for expensive lunches, drinks, etc. They also said they were experienced and knew what to say, so I would have a better chance of getting a deal. And they had their own contract lawyers, specializing in royalty agreements, to protect my interests.
I fell for it, hook, line, and sinker. I took out a personal loan to cover the cost, from a financing company that turned out to be owned by them. It took me 2 years of high monthly payments to pay it off.
And what did they actually do for me? Did they contact all the big name baby product companies like Gerber or Fisher Price? No, they contacted publishers, like the one that produces Parents magazine.
They mailed out form letters to the editors of magazines targeted at the consumer that would be most interested in my product. They never contacted a single manufacturer. Those "inventors help" companies do this all the time, for any and every product idea that comes through their doors, no matter how good or bad the product idea is. The magazine editors are used to it and know it's all crap and toss every letter in the trash without ever opening them.
And they tied my hands for 5 years, preventing me from doing all the work myself, otherwise I'd still have to give them a large cut of my royalties if I succeeded in finding a company willing to manufacture it, on my own.
So I decided to wait till the contract expired. There was no way I was going to let these swindlers have another dime.
Before my 5 year wait was up, a conversation with someone made me realize that my great little invention had no hope and would cause the death of many innocent babies that had idiots for parents. The more popular my invention was, the greater the potential for it to kill, because stupid people that don't watch their kids properly and don't follow instructions, would end up using it in cribs and playpens and leaving their children unattended for hours, or using it in car seats while they were driving and unable to pay attention, resulting in strangulation deaths.
It was perfectly safe for use by parents that actually watched their kids and only used it in a stroller where they could watch what was going on.
If my invention had made it to market, I would have no control over it and no way to stop stupid people from buying it and killing their children with neglect. My product would be blamed and not the neglectful parents, and if it became a popular product the CPSC recall could have been huge, costing whatever company that produced it enormous amounts of money in recall costs and defending lawsuits, and ultimately, cost me a fortune, too.
And I would have these deaths hanging on my conscience for the rest of my life. I would never get a peaceful night's sleep ever again.
So that is why you can't buy my invention and why I never became filthy rich.

Then someone finally picked up the line, and it turned out to be the most incompetent idiot I have ever come across, at any ISP, beating even the AOL guy from some 3rd world country that told me to make a backup of all my husband's emails (since he had the smallest amount), delete the originals, and replace them with the backup copy, in order to fix my dialup. And when it comes to incompetence, that AOL guy is a hard one to beat.
As a developer, I can't help but be more than a little bit bothered by the fact that some bloggers chose to direct link to application download files (.zip, .exe, etc) in some of the articles they write, rather than the page on the developer's site, in which the download links can be found.
We, as consumers, have a vested interest in the products and services we use and the stores in which we shop. How much of an interest depends on how we feel about it. The more we love a product, store, or service, the more of a vested interest we have in its long term success. 
Now take a look at the products and services that you currently love. Do enough people love these things to guarantee its success in the marketplace, long term? Are they going to be here tomorrow? Are you going to have to go through the pain of losing another favorite, yet again? Is there anything that you, as a consumer, can do about it?
