It's just a machine. There is no crusade against workers that is motivated by the system itself, only by its actors. The idea that the odds are always stacked against workers isn't true. It's entirely dependent on how you build the machine.

The behavior of the central bank is pretty telling. Low interest rates are pretty much inaccessible for the majority of people. It's basically free money into the hands of wealthy and large corporations. The exact opposite of what you need to stimulate an economy from the worker side first.

There are various reasons for a labor surplus in developed nations. Urbanization, globalization, lack of real estate and lack of employer provided training. The end result is young and old going to college trying to obtain self funded "job training". This makes the situation of those who don't go to college for "job training" very precarious since the job market doesn't want them. I put "job training" in quotes because the overlap between what businesses and colleges want isn't that great. After everyone finishes college we run away from our declining hometown and move to next greatest city where all the new jobs that need your fancy credentials are. Cities aren't prepared and some of them even don't want you, forcing you to find your own way into the city which often displaces existing residents. There is a form of extortion going on. Your hometown sucks and all the best jobs are in a place where you are being charged extreme amounts of money. Money alone isn't the problem, the lack of housing causes externalities like a large homeless population. It's a lot of pain only to be told how you don't deserve the money and how the existing residents hate you for figuring out a way to go against their selfish wishes. The vast majority of people don't even get into this "paradise". Their remaining hope is to simply take advantage of the odds being stacked them and engage in the same activities as the rich but they are looking for greater profits since their investment base is so small. People are looking for 10x cryptocurrencies, GME as a 15x pump and dump and lots of other risky strategies that only make sense if you don't have enough wealth to care about protecting it.

Economies are fair towards workers when there is a surplus of jobs. If there is a way to create jobs artificially, people will still favor the highest paid ones that are accessible to them. Therefore one way to stimulate the economy would be for the government to simply analyze how much economic value can be extracted from the average unskilled worker today and decide on a reasonable wage. Since the jobs are wholly artificial they can be used to do any work. A good starting point is real estate and public infrastructure. If there is a way to generate at enough value in the process to equal or exceed the economic value of your average worker then you can hire an infinite amount of workers who are willing to accept the government sponsored job. Will this drown out private companies? Probably, but it would primarily get rid of companies that are unable to generate more value than the government from a worker. Since the government isn't looking to maximize returns in every single industry branch there will be lots of opportunities for private companies to outcompete the government and thus reduce the number of people being dependent on government jobs. Since we are assuming a net positive deployment of government money there is no restriction to how much money can be obtained for financing. Even in the extreme situation where one would assume that the money is being printed from nothing the expected inflation could be well below what critics assume. However, if inflation were to suddenly pick up and significantly exceed the target 2% inflation rate then the jobs program would have to be canceled or reduced, mostly because it succeeded at what it was trying to accomplish, namely achieving full employment, but also to no cause price instability.
