Take out a FLIR imager and observe that every window is a black hole compared to even poorly insulated walls.
Doing labor has been stigmatized in most of the world for the last few thousand years. You could be excluded from "polite society" on the strength of a rumor that you personally produced goods you sold.
Of course, for most of history, there were a large number of people who knew they stood at the bottom of society and so were willing to do these sorts of jobs anyway, but that's not quite the same issue.
Besides, I think the comment you were replying to was really about the almost complete absence of post-secondary "technical education" in the USA, in particular when compared to countries like Germany.
Are these two different phenomena? If there are more glaziers in Armenia than there are in America, is that because Armenia sends the message "glaziers are winners" and America says "glaziers are losers", or because America sends the message "no matter who you are, you're a winner, and therefore you shouldn't be a glazier" while Armenia is fine with telling its losers that maybe winning isn't for them and they should consider being a glazier?
In a country that sends the message "being a plumber means you're fairly stupid, have no other talents and are doing a nasty, dirty usless job", people won't aspire to being plumbers.
Note that in the US at least, experienced & skilled plumbers are paid above median income (in some cases, a lot above median).
Something analogous is true in India, where men are willing to take substantial pay cuts (~50%) in order to hold a white-collar job instead of a blue-collar job. They do that because women don't want to marry blue-collar workers.
Focusing on income levels in marketing to the men would seem to be misplaced.
I am guessing the person above got a quote for premium custom windows in a large house.
I have odd-ball sizes in my home that aren't double-hung style, and basic vinyl double-pane windows were about 1,000/ea on average.
Currently more and more houses do triple glassing by default in Switzerland. Double glassing is already done since the 80’s and mandatory for all new house since a long time.
Obviously its more expensive so energy saving standards and energy prices have a lot of impact on how houses are built or renovated. Especially in Texas energy is cheap and I can see that there are not a lot of incentives to invest in lower energy usage by building more expensive.
Definitely one of the more 'wtf' moments when I moved.
