Although those words are not quite right, if we examine further, there is nothing wrong with what the OP said that in certain companies many employees are treated like slaves without any progress in their lives to be able to advance further.
It is true as you said that employees are the main pillars for the progress of a company, but we must also realize that most employees do not have career development even though they have dedicated many contributions to a company.
I agree with OP to a greater extent that salaries are meant to be baits to keep workers working till the end of the month then another one is being paid. When I compared the Standard of living today which has skyrocketed. You can't fathom the fact that people are really under a kind of slavery or neocolonialism working for some sort of capitalists out there.
This matter of discussion is mostly related to those working in private companies. In most countries around the world, it hasn't paid them right but plenty of these private company workers do not seem to have any choice of the situation rather than manage what comes to their table.
Thats how life cycle works on which it is really that something that you would really be needing up because on the moment or time that you would really be able to graduate on college, then the primary thing that comes up into your mind is on how to secure a job directly on which we know that there's no other way that you could really be having that startup or headstart on building up your life specially if you do have those kind of targets or hopes on making your own house or would be saving up for your marriage life or whatever the things that you do have in mind. We cant just that able to ignore it out those kind of things and thats why despite on having those kind of bad impressions towards work or simply with that 8-5 job cycle then its something that you wont really be caring that much specially on the moment that you do need up money.
The main thing that comes up into your mind is to have job because surviving on this shit economic status or condition is something that will really be your main priority. Doesnt matter if it would be taking
up all of your time or simply your independence because survival on day to day basis will matter the most. There would really be just that those individuals who would thinking out of the box and this is why they would really be coming up with this kind of extra steps on achieving something that others dont mind of.
