Wanted to add to this as well: In 20 US states, the minimum wage is 7.25 an hour. If someone is working minimum wage, this represents almost three weeks of work- more, because of income taxes. It would represent the consumption of, like, 20% of your gross income?
So that's going to kill people, either directly or by overwork.
After doing some cursory research, I've identified uBlacklist as a potential tool for curating your search results. I have seen some reassuring things about it. If anyone else has suggestions or comments, they are welcome.
