Solidarity is not some fuzzy leftist ideal. It is a defense against arbitrage, the only one that is reliable and effective over time.
Solidarity is not easy: It is a compromise among people with a shared interest, a sacrifice of narrow individual advantage to avert a greater compromise with an adverse interest.
Solidarity is always available, even when political means—which might have been simpler—have been captured and corrupted.
Solidarity is our only permanent weapon against tyranny.
