> TL;DR: The more the delay between investment and revenue generation and the more capital intensive it is, the worst. I think you're talking about high interest rates, not high inflation. High inflation means that, when you start generating income, you'll generate a higher income than with lower inflation. This, by itself, helps you repay the cost of your machinery faster. Usually high inflation also comes high interest rates, and that creates a problem if you have a delay between investment and revenue, but not inflation itself.
