Currently MLS is Top 15 in the world in team salaries (top 10%), just behind the CSL and Saudi League. In terms of quality, I couldn't tell you, since we can't seem to make it out of CCL to compare against other Confederations. They're trying to raise the quality, but they don't want inflation getting out of hand where they are overpaying for domestic talent. The overall domestic playerbase is improving so they are due for a raise based on performance, like Rooney said.
