If by “most” you mean “more than 50%” then the answer is, just barely. I think about 55% of Americans pay federal income tax these days.
Your personal opinion doesn’t count.
Federal income tax is not the only kind of tax.
Doctors study some basic science, but very few are actually scientists. There’s a big difference.
Saw this on an engineer’s desk the other day “science without engineering is just philosophy.”
I attended a jazz concert a couple of months ago (an unusual thing for me, as I’m more of a classical music guy). During her between-song patter, a vocalist slipped in a quick “Go Bernie!” and the audience erupted in applause and cheers (except for me; I’m a Hillary supporter, and I’ve learned to keep quiet about it when I’m around my artsy friends).
My experience is that folkies tend to be intensely political, jazz types somewhat less so, and classical musicians vary from mildly leftish to apolitical. The classical nerds also dress badly, drive funny-looking cars, and think Gilbert and Sullivan operettas are way more hilarious than that foul-mouthed Amy Schumer person everyone’s talking about, but that’s a topic for another thread. 
It’s not even the only kind of Federal tax levied on personal income.
Speaking as one myself, in my experience teachers trend more liberal than the population at large but not tremendously so. More than anything, a lot of teachers are just weird.
The other thing is that people act like liberal/conservative is neatly defined, and it isn’t. The guy who teaches across the hall from me fits most stereotypical definitions of conservative, until you get to economics in general and unions in particular. Then he sounds like if Bernie Sanders spoke like Samuel L. Jackson.
Strawman much? I didn’t say universally liberal, I said political leaning and age is highly correlated. See here:
I don’t doubt that but notice for example that one of the biggest antivaxing hotbeds is Orange County right outside LA, which is super conservative.
No, but there’s this:
That’s a nice anecdote but does not follow the general trend. Browse down to Engineer and see the breakdown.
On a personal opinion note, I’d say I have to strongly disagree with you. Engineering definitely requires “starry eyed dreaming and wishing”. Otherwise what motivates you to design something new? What keeps successful businesses on top are forward-thinking individuals who create the next market by envisioning it and implementing it through execution of scientific and mathematical concepts and rules. Time-honored engineering philosophy of kaizen (continuous improvement), is precisely what Progressivism is all about. If in fact we could have even more kaizen in our political system, we’d be unstoppable (as a country).
Your personal experience in this most definitely reflects an age phenomenon, ie you are an older individual who have older co-workers in an industry that got whacked by externalities (globalization), so the natural psychological reaction is to turn curt and conservative, instead of punching back.
Conservativism and religiosity are highly correlated and the whole motivation for conservatives to participate in our political process is to turn society back to what it was in the copper era when the majority of religious texts and concepts were canonized. Frankly as an engineer myself, I never aspire to build the next ground-breaking pyramid or whatever.
Oh no? Given that this is IMHO, I’m going to introduce you to my little friend:
I like the quote (not originated by me) - “Scientists discover what IS… engineers create what never was.”
Based on political discussions online, especially during the very early internet (i.e. Usenet) where software engineers were a very large fraction of the participants, I’d say that they strongly trend libertarian. Perhaps not a majority, but certainly a much higher percentage than the general population. I’d say this is an occupational hazard. Libertarian philosophy has always struck me as very black-and-white thinking. Everything either good or bad, little in the way of a middle ground. Just like computers, where everything is either true or false (1 or 0).
I once dated a woman who was a doctor (internal medicine). She said there was a lot of variation in political affiliation in the profession. There’s a divide between surgeons and specialties like internal medicine, family care, etc. Surgeons make more money, are more likely to be male, and tend conservative/Republican (at least on economic issues).
In addition, internalists get to know their patients more closely, whereas surgery often is less personal and more like changing a tire on a car. Consequently, surgeons are less likely to favor socialized/universal healthcare than other specialists.
With doctors, they trend conservative I think because 1. they go into the profession with an eye for helping others. 2. While they make good money they had to work very long and hard for it 3. Their are many who want to take their money. 4. They see the results of bad decisions.
I read that years ago right before AIDS got big it was the gay doctors who were raising concerns about sexual practices in the gay bathhouses and how a disease would quickly spread.
Yep, that’s conservatives, always wanting to help others.
I’ve run into social conservatives at kink events. I’m not talking about people who don’t like unions or immigration, or do like guns or free trade, I’m talking about people who oppose (whether outright or with the ‘I just don’t see why they need it’) gay marriage and support the various transphobic bathroom bills making the news now. When someone routinely goes to events that make a point of turning restrooms all-gender in rented space if they can but supports genital inspections, birth certificate checks, and appearance enforcement for using the bathroom anywhere else, there’s clearly some cognitive dissonance going on.
In my experience, it’s indeed often been conservatives donating or volunteering. YMMV.
In my experience, it’s often been liberals too. Wanting to help others is not unique to conservatives. If it were, all the teachers would be conservatives.
