And for some individuals, it would be an unwise choice to NOT enroll. As with health insurance, no one thinks they need it until—oops!—they do. Letting people opt out means accepting a large percentage will misjudge their future needs. The consequences this has on them and the rest of society is worse than the converse.
The poll question seems too easy.
I’ve seen my math. I haven’t seen their math. As the old saying goes, figures don’t lie but liars can figure. Anyone with an agenda can make up numbers.
If we are humans and act like humans and thus care for others, SocSec is a necessity. Sure, go ahead and get more and better retirement options, no problem. But since people who care are not gonna let the elderly starve and freeze on the streets, SocSec is the best option.
My employer only matched 2/3 of my 401K, while he matched 100% of my Social Security. So, that’s a win for Social Security. If I had a big portfolio, some of it would be in something as safe as T-bills.
Also, since not everyone is a smart investor, what happens if they invest in crap securities or sell at the bottom? Lots of people did in the last crash, after all. Not a problem with Social Security.
People stop investing in their IRAs, or they take money out in hard times. You can’t do that with your Social Security. What would you propose to do for those making bad choices?
Those of us who can afford to certainly have lots of our portfolio in riskier and higher yielding investments. But we can handle it if some of them go south. Not true for poorer investors.
The same as if China had bought and cashed in a T-bill instead of Social Security.
Allow me to demonstrate my ignorance of America. 
Agriculture - could that not be delegated to the individual States? Perhaps some hived off to Commerce.
Homeland security - split between police, Customs (i.e. Treasury), and Defence?
Interior - could not parks and the like be delegated to the individual States in which they reside? Ditto reservations?
HUD - why is the federal government involved? Surely that’s a matter for the States?
Ditto transportation.
You’ll note that I’m not suggesting removal of any; rather a transfer of responsibilities. Subsidiarity, as the EU calls it.
Once again, it isn’t an investment. It is insurance. Comparing the return on savings account rather than paying for car insurance is beside the point.
It is kind of an odd insurance, since it covers everyone who makes it to retirement age. Survivor’s benefits are closer to insurance. It is really more of a plan to force people to save for an inevitable retirement, while forcing employers to contribute. To which you can add some degree of redistribution since the lower earners get relatively more.
I suppose it was called insurance to sound less socialistic. Though perhaps it can ve viewed as insurance against dying hungry and homeless.
The Department of Agriculture is pretty tightly tied to national security - ensuring that the country and military has the food stuffs that it needs in order to survive through a war, global catastrophe, etc.
Reservations were established in a deal between the Federal government and the relevant tribes.
Parks could probably be granted to the state (and it would make figuring out permits a lot easier if they did so). Though, I don’t know that there’s any real cost savings to be had by handing off the parks and, I suspect, the parks are safer in the hands of the Federal government because they are further from local interests who would want that land to be used for commercial purposes.
I agree on HUD, but transportation - highways, railroad tracks, etc. - cross state boundaries. In the case of these long distance routes, management and oversight by a central organization makes the most sense. You also have shipping, etc. from foreign lands. (JFYI, most transportation is owned and managed by the state.)
lol that someone says we could do without the Department of Commerce. More than half their budget is spent on the NOAA - those people who collect and publish weather data, and provide not just weather forecasts, but hurricane and tornado warnings - and on the Public Safety broadband network, which connects first responders everywhere.
