I just read about Singapore’s Progressive Wage model and must say, it looks like a decent alternative to a bare minimum wage in that 1) there is a minimum wage baked in and 2) workers can increase their wages by increasing their skills.

Individual states in the U.S. could conceivably experiment with something similar as opposed to a flat minimum wage.
The objective of introducing the Progressive Wage Model is to increase the salaries of workers through the enhancement of skills and improving productivity. Progressive Wage is enforced via business licensing (as opposed to legislation). This model was designed to enable rank and file workers to climb the wage ladder, and provides for a minimum wage.Wiki: Progressive Wage
