Thanks, Johnny G! Can't be said often enough!
To wit:
There's a fundamental difference between unions in the private sector and unions for government employees. It's apples to oranges.
Government employee unions are in effect "bargaining with themselves" since they exercise disproportionate influence in electing the political officials with whom they bargain, whereas private sector workers normally are bargaining with company officials whom they don't elect.
His understanding of this fundamental difference explains why even FDR himself, the greatest of all liberal/progressive heroes, was unalterably opposed to unions for government employees.
PS: Let's be careful not to call them "government workers." While many do in fact "work," a lot of them are simply "employed" without regard to any particular real work.
