We can redistribute profits from investors to low wage workers like the people who clean toilets, but the consequence of that is lower return on investment, and with it, lower rates of investment/economic-growth.
In the long, policies that lower economic growth rates are very detrimental to all classes of workers. What increases wages for people like toilet cleaners is high levels of production relative to population.
Investment is the mechanism by which we increase production, and profits are how 1. resources are distributed to those who are most effective at growing the economy's level of production 2. people are incentivized to invest to increase production.
There's no escaping economic laws, and no free lunch from policies that redistribute income from high income earners to low income earners.
The market forces that determine pay are more competition between folks that hire others to clean toilets. If all of your competitors pay twice as much as you, you might not have quality employees... or any at all, if a job is readily available. If you have a lot of folks desperate for income, you can pay less. If there are few folks that are willing to clean toilets, you probably pay more. You could go without folks to clean toilets, but your average Western accountant probably isn't going to clean the office toilets or breakroom willingly unless it becomes standard for office jobs everywhere. Many places simply cannot leave dirty facilities - and in some jobs, you probably would rather have separate staff cleaning (hospitals, for example).
Luckily, there are a lot of levels between "unregulated, free-market-will-take-care-of-it" and complete control from a central authority. Minimum wages, worker rights, workplace safety, safety nets that ensure less desperate people, and so on.
