"just what is the l'azy left' anyways?
I think it's those that seem to always say "the government should...," or, "they should do...," or, "what we should do..."
It's never "this is what I'm doing," or, "this is what I'm going to do..."
and, just who decided what is lazy, and what isn't?
I did.
That's why I put in the preceding "I think."
isn't this america...life, liberty, pursuit of happiness?
Yes. But that's kind of important; "pursuit."
That means personally doing something.
This isn't "America...life, liberty only for those that who want to convince others to change or sacrifice to subsidize or guarantee their happiness without any real or meaningful personal cost or effort."
is happiness working nonstop to buy kitschy plastic crap we don't need and didn't know we wanted?
For some it is.
is the desire for a more relaxed life in a paradise unsullied by the ravages of the 'non lazies' not a fair pursuit of life, liberty, pursuit of happiness?
Sure.
You just have to create your own unsullied paradise.
is happiness slaving away to make others richer and more powerful so they can have more control over you and your paradise or someone else and their paradise???
To some it might be.
Other than that, everything you describe here has been particularly facilitated by government intervention.
are one's pursuits any more or less valuable than another's?
Inherently, no.
The individual subjectively defines the value of their pursuits, and through voluntary (or involuntary) group effort subjective pursuits can be achieved.
if your pursuits get in the way of others' should you be allowed to continue with them?
That's what guns and the ability to pay them off or convince them to pursue other interests are for.
does circumstance change opinions?
Of course.
Anything and everything can change an opinion.
should it?
Good luck with that: getting people to never change their opinion, or forcing/convincing everyone to share the same opinion.
how are these parameters set?
Poorly, usually with whatever works at the time that leads to the least amount of bloodshed.
how should the be set?
Ideally by an omnipotent, omniscient, immortal, beneficial, merciful, loving, altruistic, benevolent tyrant with nothing better to do but above mortal concerns.
who gets to decide?
Each individual, and/or group the individual cedes power and freedom to.
