To be fair, they were as bad or worse in the '50s and '60s, but at least they had other things going for them (styling, performance.)
I was a kid, but avocado green and harvest gold appliances are what stood out for me. Underpowered and poorly built large american cars kind of jumps out as well.
There are better, more-obvious answers but for me it’s the architecture and interior design (shag carpet and swag lamps come to mind). Along with subdivisions and split-level houses.
or… Elton John.
You are all wrong.
The answer is Farrah Fawcett! Specifically Farrah Fawcett-Majors. Jill Munroe AND Steve Austin! 
Watergate. I was obsessed. I just added another book on the subject to my Kindle.
Also Star Wars and incredibly uncomfortable polyester dresses.
An angry, defensive President with an enemies list.
A long-drawn-out overseas war.
A massive drive to legalize marijuana.
Self-absorption as a national pastime.
I’m so glad everything’s changed!
The 70s, you ask?
That’s being 15 and flying down a red dirt Georgia back road ridin’ shotgun in a black Formula One Trans Am with the T-tops out, wrecking my long Farrah Fawcett 'do while wearing a halter top and cut-offs, with Freebird blaring outta the radio.
That, and sucking pennies because your cousin told you it would take the liquor off your breath.
I know, I know…there are people right now in South Georgia who live that every day because they still think it is 1978.
Thankfully, I did move on, but my 70s memories are stellar and golden!
As for the 80s…well, that’s another thread!
One website I came across said, “art that clashed with everything, including itself.”
Narcissistic baby boomers
Good movies. Bad music.
I was a child in the 70’s. When I think of the decade my first thought is the colors. There are just certain clothing and decorating colors which were horrifically in vogue at the time. Avocado green, burnt gold, various shades of beige and brown, all within a certain palette and generally ombre’d down to a brownish hue. And Orange, it was a very orange decade. . .
First thing that leaped to mind is how houses were decorated. Harvest gold refrigerator. The bright flowers on my sister’s wallpaper. My orange clock radio. My sister’s night stand was a barrel painted white.
This. This and everyone cool dressing up like the Fonz.
Leisure suits. Yes, I owned a couple. Along with Qiana shirts and platform shoes.
Lisztomania.
The ultimate distillation of the peak of '70s excess at the decadent core of the decade. If the '80s were characterized by excess of greed, the excess of the '70s was all about sex, drugs, and rock-‘n’-roll. Lisztomania is a crash course in what that was like.
Ironically, by the time Ian Dury came out with that anthemic '70s song in 1978, the era of sex-drugs-rock-‘n’-roll excess depicted in Lisztomania was over and the New Wave, including Dury, had abruptly shoved it aside.
Great music, better movies, but if you are looking at specifics, Fleetwood Mac and Chinatown are what I think of when I think “the 70s”. And Philly soul, and that “scratch guitar” sound I associate with funk.
Hanna-Barbera cartoons drag me right back to the 70s.
Hong
Kong
Phooey
Number one super guy.
I was born in the '70s. Mother made me wear plaid. I had a stupid haircut. It made me really mad.
Whoooooaaaah Disco!
Everything in this song basically
My first marriage.
Neither was exactly a high spot in my life.
Mood rings.
Creepy mustaches
Skate rinks
Kiss
