1) Most jobs are low level jobs though. They are not the exception, they are the rule. Meaning that employees in general don't have much of a negotiation power.
This isn't a lack of liberty in the context of the study in the OP.
But the legal right to apply for jobs wherever one wants is
liberty. If one wants to bargain harder, one must offer greater
value. Being of low value isn't something to be cured by
having government imposing restrictions upon business.
The worker has the liberty to improve & negotiate.
Liberty isn't about government providing largesse, even
if that's something we decide is good.
2) Selecting who you are going to work for depends on the current state of the economy where you live. Sometimes you can't afford to be a choser and other times there isn't much of a distinction between the ones available.
People have the liberty to move to where jobs are. But about
this....one thing that interferes with this liberty is government.
It imposes high real estate transfer costs upon home sellers.
And if the market is down, & one borrowed from government
(eg, Fannie Mae, Freddie Mac), government will not bargain
to reduce principal for underwater buyers, thereby trapping
them in a location.
Private lenders to bargain principal & interest. Been there
& done that. This is liberty.
3) I like the system we have in Brazil. In simple terms, both the employee and the employer need to let the other part know they want to terminate the contract around 30 days in advance, unless there is a just cause (think of the employee stealing from the employer, just to cite one example). The employer can also immediately fire the employee for any other reason in which case the wage for those 30 days is still owed to the employee as if they had worked those 30 days. The employee can also quit right away, in which case, the wages for those 30 days will be discounted from whatever the employer owes to the employee.
That is a case where the country decided that a reduction
in liberty is of value. But it is still a reduction in the liberty
of the business...one that is not reciprocal. And again,
this is confusing worker security with liberty.
From post #91...
I sense that some here are confusing liberty with morality.
And this leads them to believe that which is more moral,
has greater liberty. Not so. Tis better to recognize that
sometimes restricting liberty is useful, eg, licensing of
professions such as doctors, lawyers, CPAs.
We'll have no total liberty in any government. I favor
balancing liberty & limitations more on the side of liberty.
