Some things get worse, other things get better - from a libertarian perspective.
Growing national debt, executive overreach, the Obamacare quagmire, leftist brainwashing in schools - sure, all that is happening.
On the other hand, we have historically low crime; gun ownership is more widespread and more secure than ever; free trade keeps advancing, however fitfully; right-to-work legislation is spreading; the Idiotic War on Drugs is ending; no major tax increases are in sight, and there is a consensus that corporate taxes ought to be reduced; gay rights issues (the last area where the Left was appealing because it was basically right) are being taken off the table, etc, etc
It is really a mixed picture, not altogether grim. There is certainly the immediate threat posed by Trump/Sanders populism, but I believe it will be neutralized one way or another.
Short term, a lot of problems. But long term, I feel rather optimistic: We have been through much worse; America is resilient.
