ToddsterPatriot, the Federal median wage rate to generally affects all USA wage rates to some extent. It has the greatest effect upon the lowest paid third of USA wage earners. Due to an increase of the minimum rate, the median rate of that entire third of USA's wage earners increases. This in turn causes wage increases for employees within the next, (i.e. the second) highest third of USA's wage earners and USA's median wage which is in the middle of that second bracket of wage earners.
The increases for those within the second population of wage earners' bracket is proportionally (to their wages), less than the increases for those within the first bracket. The increases for those within the third population bracket, (i.e. the highest earners') bracket is proportionally to their wages, less than the increases for those within the second bracket.
If you didn't understand post #53, I doubt if this post will be of much help to you. Regrettably, I apparently overestimated your abilities to comprehend wage differentials, or median wage, or economics
