Foundation shouldn't be scrapped.
Most of you on this post seem to be the sorta C and higher achievers, so of course, all of you should be entered for higher tiers to get your best possible grade. I have friends who could be getting Bs, but are instead entered for foundation which is of course, limiting them. But this issue should be taken directly to your teacher and if you feel that strongly you should do higher, then stop sitting on your backsides complaining and get parents to complain to school and make some actual progress.
Foundation is designed for pupils who are just looking to pass, and some of the skills that higher papers ask you are just too much out of the reach of these sorts of pupils, even though the grade boundaries are lower and seem easy to achieve. Take science AQA for example, the higher papers require you to apply knowledge, whilst foundation just needs you to recall information. If you're hoping to go into an apprenticeship or a BTEC unrelated to science, then all you want is a pass right. So the foundation papers give the opportunity to get a pass on memory and revision skills. It's much better than putting a pupil of a low ability through the strains that everyone else can find quite easy on the higher paper. Besides, higher papers are designed to get you Bs and As and A*s, if you're only aiming for a C I don't think there's even much point, especially if you struggle with it.
Same with maths and English. If you're one of those who likes to complain about how trigonometry is irrelevant for your future compared to simple numeracy skills, then foundation maths is designed for those pupils who just want to get a C to show they have some mathematical ability that could help them in their future jobs. The AQA English language papers ask you to use more basic skills, like less language analysis. And to be honest, not all jobs need you show you can analyse language. So, foundation is also relevant for this subject.
I'm guaranteed a full set of Bs and higher at GCSE, but In French I was entered for Higher reading and listening foundation. I'll still get a B though, because my coursework is an A. But I chose foundation in this case because I struggled that much with the quicker speaking, and as I'm not taking French to A Level I don't really need to give myself an ego boost and do higher. I just want my B.
Maybe if you all actually thought into the purpose of foundation, you'll get it. It's meant to be easier for a reason. But if you find it that easy, go do higher and get a B or A or something.
