American supermarket employees (especially in California and Illinois by personal observations) would kill to negotiate contracts on a sector-wide basis.
The streamlined version of sector-wide labor agreements -- the French/French-Canadian practice requiring non-union firms to operate under agreements worked out by unionized firms -- is ready and waiting for America's seamless transition to a fair and balanced labor marketplace. Economies from South America to South East Asia use mixes of mostly unionized to mostly non-unionized sector-wide rules -- some confined to certain industries (sector - sector-wide) -- there's all ways to do it.
Adopting French-blueprint sector-wide here would not require -- on the run -- building a broader union base than we ever built before (as going German style, full-out unionized could). And, the French-Canadian example will always be right next store for our convenient perusal -- in an economy we can reasonably fathom.
PS. Sector-wide collective bargaining was put in place by after WWII industrialists in Europe -- not labor unions -- to keep unions from going on a race to the top. Turns out to stop the race to the bottom just as well. Wal-Mart closed 88 big boxes in Germany because it could not compete pay the same wages and benefits as everyone else. Now in practice around the world -- as far flung as Argentina and even Indonesia.
Average income actually doubled since -- as real world 1968-Americans might have anticipated. 2007-working Americans -- if and when somebody troubles to fill them in on their missed prosperity (50 to 90 percentile incomes could mostly have done significantly better; 25 to 50 percentile incomes mostly held plus a little) -- will have one culprit to mostly contemplate: the race of under-powered (ultimately because under-informed?) labor to the bottom.
[ * 12.5% of American incomes are officially reported below today's, decades irrelevant, federal poverty standard: three times the price of the cheapest emergency diet -- dried beans only please, no canned! -- try the 2002 book Raise the Floor for realistic poverty parameters. ]
When, when, ever, ever, is this world going to catch up with the import of something called ECONOMIC GROWTH -- when viewing these kind of long, long term (80 years out) federal spending projections?!
Economic output per person doubles every 40 years -- which means quadruple every 80 years..
By 2082 (close enough to 80 years), someone whose grandparent earned $50,000/yr should be able to make $200,000/yr doing equivalent work (and that's not even counting "flying cars" for the same $25,000*).
Federal spending that takes 18% of a $50,000 income today leaves the earner with $41,000 for everything else -- federal spending that will take 36% of a $200,000 income tomorrow will leave the "suffering" tax payer with only $128,000 to spend on everything else (and that doesn't even count super potent medicine).
Three times the income left over, "3D" TV for the same price*, super healing: shouldn't we all glad we wont live to see those "terrible" days?
[ * Technological progress isn't counted by inflation (objections of the Gingriches of the world aside) because it would be:
a) inhuman: we are not going to give people living on indexed incomes less money to buy potatoes because they they can aquire a better TV for the same (adjusted) price;
b) unworkable: only God could put together into one inflation number that my new Timex watch costs half what the Timex of my youth (50 years ago) cost while it is 10 (?) times better -- and man would not find God's tech-included inflation number useful, anyway, unless it were broken back down into the two original interesting quantities;
c) unnecessary; when average income grows 20% over an average decade, there is no harm in leaving the free gifts of technology out of the inflation spec ("Mr. Sky is Falling", a.k.a. Chicken Little, Newt Gingrich who is panicking that old pensioners getting a few dollars of extra value out of their checks will cause civilization to crumble, aside).]
