It really depends on your definition of wealth. Most engineers I know clear 100K+ pretty easily after a few years of experience. If you're in a hot market or sector, you can easily earn $180k+ after 5-8 years. If you produce consistent value for a business, $225k is definitely achievable.
Understand that by making $100k+ you're basically in the top 10-15% of earners in the U.S. [1]. Make $180k/yr and you're in the top 4%.
And realize that plenty of people who make >$150k spend like crazy trying to keep up with the Jones. Plenty of people who make $80k/yr spend wisely end up having more "wealth" in the end.
