It's not supposed to be equal in that way. When you're bribing someone, the equality comes in the form of the amount of the bribe being equal to the weight of the risk they are taking to give you the corrupt results you want.
But everyone thinks of bribery as a quid pro quo, where some amount of money changes hands in exchange for some specific act of public office. In this case, all of those trips were basically influence peddling--investing in a public official who would then be predisposed to do favors for the investor. Crow was then in a position to bring along others on these trips who would gain exclusive access to a Supreme Court justice through him, thus increasing his (Crow's) own power and influence within Republican circles. Crow was connected and could make good things happen for people with cases before the Supreme Court. This is what the Democratic leaders in Congress want Roberts to investigate, but Republicans don't want that rock overturned to see what kinds of things crawl out from underneath it. Roberts doesn't want to be the one to uncover dirt that went on under his nose for years, so he isn't going to lift a finger to find out. They'll find a way to sweep it all back under the rug--until there is a significant shift in national politics that allows Thomas to be investigated.
