[Harry Potter] How far/powerful could a Squib go/become in the Wizarding World?

What could they accomplish using enchanted items, Potions, Herbology, Muggle Technology, a House Elf assistant and any other means. Most wizard jobs don't really require magic just knowledge of it. Like the real world the only problem is accommodating the disability. I'm sure they could fake it to an extent and i'd love to hear your thoughts.

Someone forever ago was talking about Filch and how he might be a Squib, but he was also able to repair The Fat Lady.. A job that takes a massive amount of skill and knowledge in the non-magical world on non-magical paintings. That's absolutely amazing for a magical painting.

The problem isn't whether a squib could become powerful and successful.. It's whether the magical world would allow them to. Even with the 'good' witches and wizards, there is a lot of exceptionalism in the magical world and squibs are never given the chance to grow because they are looked down upon - like Mrs figg the cat lady or Filch who the twins make fun of because he's taking a kwickspell course to learn magic.

No wonder filch is a jerk.. He's been looked down upon and made fun of by kids his entire life.
