Just wait... eventually you will reach a point where building upgrades/land purchases cost over 100k and take several hours apiece, and you have to hire 10 engineers at 60k/10 hours apiece.
How about over one million and DAYS to upgrade? I spent countless millions upgrading my industrial buildings. Now when I see 500k upgrade, for example, I say, "Thank God, it's so cheap, only 500k!"
