This is why I.didn't want to go to in depth in the political. It essentially boils down to job scarcity versus unemployed people in the local area. Much of the US doesn't suffer for able bodies so pay remains low without government intervention. Part of that problem is the ease and overabundance of H1B visas. That drives 'skilled' labor out of their job market into lower jobs which spirals down until there is an abundance of 'unskilled' labor in a market with too few jobs.

When companies literally bring over H1B workers, and have American workers train their replacement that means there wasn't a need for that worker. Its happened a lot over the last 20 or so years.

The wage issue is terrible but it was compounded by 'Government Intervention.' Government intervention (and lack of it where appropriate) has driven jobs out of country, brought mass immigration (H1B and other programs) into times where job availability is limited, promoted policy that encouraged full time jobs to be replaced by part time, and lastly didn't raise minimum wage when they destroyed the job market.

Basically government increased demand for jobs artificially and did nothing on the back end. Both parties did something to create the problem. Democrats seem to be encouraging a partial solution, which is minimum wage increase. It still won't solve unemployment issues but it at least gets people paid. Depends on the market but it will drive some increased automation and loss of jobs but it is a fix for some issues.

This is very simplified. I could go into the complexities of why both parties compounded the wage and job market problem.
