We have had several amendments in "modern" times. The most recent in the 90s.
The one ratified in 1992 was submitted to the states was submitted in 1789 and had to do with delaying congressional salary changes. Yeah, the paragon of modern issues.
But let's look at what else has been ratified in the last 50 years:
* Lowers the voting age to 18 (26th - 1971)
Oh jeez, how about the last 100
* Presidential succession (25th - 1967)
* Prohibits poll taxes (24th - 1962)
* Grants DC electors (23rd - 1961)
* Term limits for president (22nd - 1951)
* Repeals 18th amendment (21st - 1933)
* Changes start date for congress and president (20th - 1933)
* Women's right to vote (19th - 1920)
* Alcohol bad (18th - 1919)
Really, looking at the list of amendments most of the after the initial 10 don't deal with new issues but instead just tweak the existing rules.
You might want it to be, but read the Constitution and Bill of Rights, it isn't in there.
You may want to read the 9th amendment:
> The enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people.
So, just because it isn't in the Constitution doesn't mean it isn't a right.
