This is a fallacy. First of all wages are not dropping. You're being purposefully obtuse with your words. Of course something that is rising makes something that is stationary or moving upward more slowly appear as if it's lowering.
In fact, just as almost always is the case, wages are either maintaining or increasing. And honestly it doesn't matter who it is because these a private companies, and like it or not, you have a choice to work there. If you don't like that the CEO got a raise, leave. It's a free market (kind of) and a free country.
Secondly, if what you say is true, most Americans would be making minimum wage. However, less than 11% in all groups of hourly workers make minimum wage. And that rate is 5% for people with a high school diploma.
(Bureau of Labor Statistics) It's not unions that keep us from having "miserable working conditions and wages," it's a free market that does so. Wages are part of the market. If people want talented workers they have to pay for it. That's why those who switch jobs more frequently tend to make higher wages. Labor is a commodity.
And also, the terrible working conditions and wages in third world countries are better than the alternative. In countries where child labor is prevalent, the alternative is often child prostitution. But no one mentions that. Either is sad, but working in a factory is quite a bit better than children having intercourse for money.
And the people too.
