I would argue that everyone over the age of 8 can do it with sufficient motivation and quality documentation. $10-20 and the promise of more money doing some low-effort "consumer survey" or providing "extra analytics" is pretty enticing to a massive number of people really struggling in this country.

Despite being hard-up I don't think the vast majority of these low-income individuals would agree to being so egregiously wiretapped and data mined for future political ads on youtube or bundled into some other product without better compensation.
