I recommend you read your country 's criminal code, particularly the extortion article.

Capitalism is literal extortion. It's the exploitation of the cost of producing redundancy, which lacks reasonable justification. Producing redundancy is what they menace workers with in order to receive ransoms.
For example, a landlord purchases a home to transform into a rental property. He asks consumers to pay him a ransom to be able to access the captured property. If they refuse, they have to produce a second house to fulfill the same amount of demand. Producing two houses to only be able to use one is twice the cost, a way higher price than the price of the ransom. So the ransom get paid to avoid producing redundancy. It's extortion.
There's never a reasonable justification to receive a compensation in wealth if you don't produce an equivalent amount, that is unless there's consent. An ownership of money that would allow the acquisition of rental properties isn't a production of wealth that warrants a compensation. It's not a difficult thing to understand.
Even though there's no reasonable justification for it, people capturing wealth still gain bargaining power. They force consumers to either pay a ransom or produce wealth to replace the captured one. Producing two houses to be able to use only one is twice the cost for society. This cost is higher than the cost of the ransom. This is called the exploitation of the cost of producing redundancy.
Just like there's no reasonable justification for being compensated for a sole ownership of anything, there's no reasonable justification for exploiting the cost of producing redundancy.
Exploiting the cost of producing redundancy is literal extortion, which is highly illegal.
Employer pensions don't make sense. If you want to forgo some of your purchasing powers to keep money for your later years, nobody is stopping you. There aren't any advantages in letting your employer do that for you.
