I agree, but the reality is that the most egregious offenders of consumer rights tend to control the markets they exist in, and the diligence required to effectively "vote with your dollar" is enough to overwhelm even the most staunch among us.
I've always found Ivy Lee's essay "Mr. Jones' Dilemma" to be a great summation of this problem. I'm having a hard time finding it online, but I'll link to it if I find it.
Edit: can't find the essay anywhere, but it's the intro to this book: https://www.goodreads.com/book/show/36077624-mr-lee-s-public...
