To Dupe or not to Dupe that is the question?!

So over the last few weeks in the beauty blogesphere there has been a heated debate over duplicate products that are sold at a cheaper price.  There are products that look the same when it's used and also the products where the packaging looks the same.  

Some people are saying that it is plagiarism or it is ethically wrong where as others are saying that the original brands price out a huge audience who can't afford the large price tag. 

Lets talk specifics.  The company that has been most under fire is some of the brands in the Tam Beauty family like Makeup Revolution and I heart Makeup.  Kat Von D has released a YouTube video where she says that her makeup line is something she has worked very hard on and that being ripped off doesn't seem fair.
The palette on the left is the KVD Shade and Light palette and the one on the right is the Makeup Revolution Light and Shade palette

Here is where I stand, dupes in the makeup industry have been around for a long time and it's not just the beauty industry.  Almost every other industry does this. Look at fashion:

Here we have a designer dress from Mark Jacobs and the high street dupe from Topshop

What about breakfast cereal?

Here we have Kellogg's Frosties with thier dupe from Lidl - they even have a tiger on the front.

Last but not least Cola

This is Coka-Cola with Freeway Cola from Lidl. 

You don't see these companies worrying or complaining.

I honestly don't see an issue with any of this.  KVD's Shade and Light eyeshadow palette retails in the UK for £37, the Makeup Revolution Palette retails for £8.  The price points target two completely different audiences.  KVD is not going to lose custom because of this dupe, if anything she should be flattered - the fact that this dupe has been created means that her palette was successful.   I have read comments that people have left saying that although Makeup Revolution have not broken any laws (you can't patent the layout and colours in a palette - just the formula) its not ethical.  Here's a question, how much are the high end products marked up? Do they need to be that expensive? I think probably not. 

Had Makeup Revolution called it the 'Kat Von DEE' palette then yes that would not be a good thing you can't really play on an established brand name.  Similarly had they called their Blushed Hearts, Two Faced again I could see a point.

But they did none of these things, all they have done is make expensive things both affordable and of a good standard. 

My final thought is this:  I occasionally treat myself to high end products, but I can't afford to buy them all the time.  Brands like Makeup Revolution means that I am not left out of the beauty world simply because I don't have money to spend on expensive things.  I get to have fun and play with makeup like everyone else, surely this is not a bad thing?
