Oh I would love to create a search engine that would preserve the privacy of its users, but I just don't foresee Google doing that. I'm aiming at studying Theoretical Cryptography, with an interest in MPC specifically, so this would be right up my alley, but my pessimistic world view tells me that any efforts to create more secure and privacy-preserving services will fail because of institutional opposition and low market demand.

We're on the same page. There's been tons of great work in the past couple years (Smart's SPDZ and others). The financial model has to use something like a pay-per-search instead of the usual ad model (although technically even better ads could be served over SMPC!). If you're interested in studying this you're also probably interested in 1-k Oblivious Transfers (get me a static webpage I request out of a choice of k without revealing which I've requested), in Functional Encryption and also in Securely Obfuscated Programs. Also, there was a really awesome paper at CRYPTO this year: "How to Use Bitcoin to Design Fair Protocols" (http://eprint.iacr.org/2014/129.pdf http://eprint.iacr.org/2014/129.pdf) :)
