Labor, because without it you have no use for the other two.

@glennlab "Which is the most important leg of a three legged chair ? "

@FearlessFly It is not a true three legged chair since labor can exit and does without either capital or management

@glennlab "labor can exit"'
If, by that, you mean go-on-strike, BOTH capital and management have historically demonstrated that they too have their own "machinations/powers".
IMO, unions are a good (the only) check-and-balance against the other two.
ymmv

@FearlessFly Labor can exist, exit is not what I typed, merely what the site decided I wanted to type. Sorry for the misunderstanding.

28 states now have Right to Work laws. Sad.

Unions gave away their power to the demonRATs establishment during ReaGUN with Tip O'Neal stealing 5 trillion dollars in 8 years for illegal wars in 160 countries.... Unions were so powerful 1920-1978 the rethuglican party gave lip service to my union comrsdes.... Kock Bros ReaGUN Clinton ObushaObombney et al reduced union membership from over 40% to under 30% shipping jobs across borders&overseas..... when people boycott Starbuck$ Amazon McDonald's & Wal-Mart until all workers get 25 dollars per hour MINIMUM ALL 50 STATES....prEyerd hopey changey will not get us there
