"The more I get cable for me," suggests that the speaker's personal possessions or gains increase at the expense of others. It reflects a mindset of acquiring more for oneself, possibly leading to less for others around them.
"The less you get away for you" indicates that as the speaker's possessions or benefits grow, others experience a decrease or are left with less. The quote highlights themes of self-interest and imbalance in sharing or resources, consistent with some of the whimsical and paradoxical tone of Lewis Carroll's writing.
