The solutions are not unknown. They are, however, unemployed.
Thankfully. The solution of the OWIES is to tax people.
The problem with you liberals is that you expect government to do things you should do for yourself.
I grew up in a union household, back in the oldie days before unions became so corrupt even union members don't have much use for them. Do you know how they got fair treatment? They held actual strikes, when needed. And when a company was under strike or boycott, you just didnt' do business there. Consumers took it into their own hands.
Now whining to the government to make things right.
Today, even strikes aren't what they used to be. They show up for a one day protest with a big inflatable rat. (Seriously, who makes those?) and walk around with signs for one day. Then they go home, and the non-union company finishes the job.
