I appreciate the frank nature of your post. As a left leaning person (though I lean right on nuclear power, drugs, and a few other issues) I'll try to answer as honestly as possible.
> higher taxes
I'm fine with higher taxes for some purposes. As a fairly high income earner, my tax bill hurts quite a bit. Still, when I was a kid I had a single mom. She had to go on welfare for a little while, and it was rough on her. I think it's the first time I ever saw her cry.
Obviously there are some people who abuse the system, but I feel like we have to keep providing anyway. The money that we collected for those few months kept us from being homeless. I like to think it as an investment in my future by the tax payers. I've paid more in now than I took, so it worked out.
> more regulation of businesses
Not always a good thing, but I can get behind some regulations. I think the repeal of Glass-Steagall was probably a mistake (thanks, Bill), and likely contributed to the 2008 bubble burst. Things like the FDA, and OSHA seem like examples of good regulation. They're certainly imperfect, and have made mistakes. On the whole though, I think they've been a net positive.
> more intervention in housing markets
Not much of an opinion on this one.
> higher marginal tax rates on "the rich" (AKA a middle class salary here) etc.
Hillary's plan calls for a 4% tax hike on incomes over $5 million. Software developer salary is pretty good, but I don't think anyone's salary is that high.
