Unfortunatly, raising the minimum wage is like pushing on a string. It's a 20th Century solution to a 21st Century problem.
Today, increasing the aggregate cost of human labour in any industry simply results in a greater incentive to replace human workers with machine labour more quickly. Driven by "Moore's Law" it's an inevitible process fueled by the market driven imperative to reduce cost in order to maximize profit. This is the biggest factor driving the migration of wealth to the 1%.
The 21st Century solution will involve rethinking our reliance on using income and wealth to measure the value of human endevour. Progressive Penguins might try thinking less Joe / Bernie, more Andrew Yang?
