I guess everyone understands that you are talking about US phds, so no worries :)

But yeah, doing your PhD in europe may not be simpler (we have to give lectures, organize seminars etc.) but considering that you get a good pay for your research as well, it is definitely a good alternative to going directly in the industry. However, doing your phd during your masters thesis or even starting without a masters degree is very uncommon, so you usually need more time to get it.
