Here's an example of exactly how much:
Mitt Romney’s campaign won’t say if the GOP presidential candidate would have signed the Lilly Ledbetter Fair Pay Act into law, but on Sunday Sen. Marco Rubio (R-FL) — a top campaign surrogate — disparaged the measure as a giveaway to trail lawyers.
“I think that anyone who’s working out there and making a living, if you’re the most qualified person for the job, you should be able to get paid,” Rubio said. “You should get paid as much as your male counterpart, everyone agrees with that principle”:
RUBIO: But just because they call a piece of legislation an equal pay bill doesn’t make it so. In fact, much of this legislation is in many respects nothing but an effort to help trial lawyers collect their fees and file lawsuits, which may have nothing to do whatsoever to increasing pay equity in the workplace.
Bolds are not mine, this time.
Mmm. And trying murder cases is just a way for the defense lawyers to rake in the big bucks. But of course I think murder is very wrong.
Enough with the joking. The official position of the Republican Party is that "everyone agrees with the principle" that equally qualified women and men should get the same for performing the job equally well. The principle, note.
In practice, people like Marco Rubio do not want to do anything at all to enforce that principle. In practice, people like Marco Rubio are always on the side of the employers in these cases. Besides, based on the hidden Republican agenda, women should be at home and not out there taking jobs from men.
The opposition to laws against gender discrimination is an example of the wider opposition Republicans have towards any laws which might "burden" corporations. Whenever there's a choice the Republican Justices on the Supreme Court side with corporations and against workers.
