Why not unionize more work sectors to combat unfair wages/pay?

In response to poor wages/pay actors/entertainers/etc. were getting time ago before any unions were established, the modern-day SAG-AFRTA now exists to assure everyone in unionized productions gets fair pay that's contingent with overall funding.

In the debates yesterday this was brought up. CEOs making millions while employees are making pennies to the dollar and highly capped pay rates. If a movie will pay actors amounts contingent on total budgeting costs, what about any other companies being unionized and doing the same?

With the profit of massive companies we know today paying workers barely livable wages full-time or not even keeping them above the poverty line, maybe the solution to better working conditions is to unionize more working sectors or such.

Sure, maybe not everything should work this way, but perhaps if more working conditions were further relative to earnings-based pay (from the company you work for) vs. just a federal minimum that would apply no matter what (which allows big companies to profit billions and the people running them to pocket millions while you are working 24/7 to earn your minimum wage and barely survive).

I hear of no major issues with SAG-AFRTA and the film industry about unfair pay as much as, say, fast food workers protesting and the like. Maybe there's some good evidence that unionizing more work would help establish better living wages.

I mean, big studios/movies don't have problems profiting while paying mega movie stars millions of dollars. So I don't see any justifying Burger King crying because they have to pay their workers several more hundreds or thousands per year.

If you want a fairer pay system, make it solely contingent on upper-tier earnings distribution, especially when it comes to mega companies making millions/billions easily. Of course the other side can argue for higher minimum wage, but that runs the issue that -- even if so -- the scaling factor isn't balanced (Burger King still making billions to date while you work there > 50% of your life to net under $18K a year). Burger King or big companies in general can either pay people bigger pay relative to total earnings or swear people off entirely. Raising minimum wage doesn't help as much as raising earning shares relative to the surplus of profit the company makes (since most big companies people work for are likely to make massive profit surpluses accordingly).

If you let anyone "pay what they want" to workers, most companies will pay nearly nothing and keep as much profit as possible (this is what our current system is like -- only with the addition of poverty-level wages legally-implemented by federal minimums). What do you get? Peasants working their entire lives for dirt and kings ruling over them -- farfetched, but I think my point gets across here.

So I'd propose:

1.Raise federal minimum wages dramatically (up to ~200%) to combat this discrepancy and help more people earn living wages at minimum; or....

2.Unionize more work sectors/areas to assure everyone earns their fair chunk of the big pie (and makes it more likely that people won't fall below the poverty line with full-time work).

I mean if one of these two things cannot help, I don't think much of anything else will.

Also, formatting isn't working.....
