WOTC - Low income worker

I asked this question in the Wisdom of the Crowd:

What is a good way to raise the wage of low income worker?

Here are the responses: (61 Votes)

61 % - Introduce a minimum wage, like in most countries.
23 % - Stop the inflow of foreign workers 
13 % - Get the public sector to pay adequate wages and set the benchmark for the private sector.
3 % - Introduce the progressive wage system for more categories of jobs
