Assuming that most rich people are college educated or tech people (both overwhelmingly left wing), then it makes perfect sense. A lot of people have an attitude that politics is just politics, a corrupted game that can't be changed and don't spend much time researching the topic. Whatever gets propagandised in their environment becomes their belief. It happens gradually; when talking to people with a clear view on something the person who doesn't have counterarguments will just start accepting those good points - and eventually he will start repeating them. As a kid I didn't care much about soccer and yet, when asked, my favourite soccer team was the same as my friends. In terms of companies, it also makes sense for big tech and big business in general to be pro regulation and pro taxes: regulations just stifle their small competitors and taxes are mostly hitting people (either as income tax or as increased cost of goods). This is quite a futile exercise anyway, whether it was republicans or democrats, whenever they're in power they start spending like crazy (on different things). If it's republicans you can hope they won't raise taxes and won't wreck the economy, if it's democrats you can hope they will give some freedom back to people (eg. drugs legalisation, gay marriage). There are no mainstream defenders of small government anymore, unfortunately.
