Most entry level Engineers start from 55-70k here in Houston depending on what field you work in. I know a guy who was offered 95k straight out of school to work as a Mechanical Engineer for Technip here in Houston, but that is unheard of most of the time. If you are a registered Professional Engineer like myself, you can make 100k+ after 10-15 years of quality experience in your field. Making 6 figures in Houston is more than enough to sustain a very healthy lifestyle, but it all depends on how you spend your money. It's not how much you make, but how much you spend. I own a 3500 SF 4 bedroom home in a very nice part of town and it was only 260k brand new and it was a custom build. Things are really cheap down here compared to other parts of the US and the World.
I know a few Engineers who work contract for the Port of Houston Authority and they get anywhere from $75-150 per hour for construction inspections.
When i got out of school with my BS in Civil Engineering i got a job making 68k with a nice signing bonus, but i already had 7 years of civil design experience by the time i graduated because i worked for a Civil Engineering firm the entire time i was in school. We have two graduate Engineers (E.I.T.) at my firm right now who are paid about 55k a year and these guys are in their early 20's fresh out of college.

sounds right to me.
wish our houses were $260k though.
our median price is $400k (Au), and we live in perhaps the cheapest city in australia.
we've had nasty Real estate boom with foreign investors buying up properties and land making rent and home ownership very difficult for the average joe.
imagine a $300k loan when you earn $50k PA. over 35 years thats about $2.5k per month from a net wage of $3-$3.5k per month.
my brother has just finished his mechanics apprenticeship. he's looking at earning $50-$70k for his life and has no idea how he's going to be able to afford a house.
then there's rent at $350 pw and minimum wage at $570pw before tax....and thats in the cheap areas.
of course much worse in sydney.. $800k houses being paid off by 2 people earning $100k each per year and not being able to afford to go out or get nice furniture.
but, then they sell in 24 months and make $100-$150k.
crazy shit
