So looking at each MLS club here are the measures of income inequality for the 2015 season using the data from the MLSPU in the table below.
| Team | Base Salary Gini | Guaranteed. Compensation Gini | ||
| CHI | 0.564 | 0.560 | ||
| CLB | 0.342 | 0.371 | ||
| COL | 0.459 | 0.463 | ||
| DAL | 0.346 | 0.337 | ||
| DC | 0.377 | 0.394 | ||
| HOU | 0.436 | 0.448 | ||
| KC | 0.460 | 0.450 | ||
| LA | 0.777 | 0.774 | ||
| MTL | 0.367 | 0.368 | ||
| NE | 0.619 | 0.625 | ||
| NY | 0.419 | 0.450 | ||
| NYCFC | 0.777 | 0.772 | ||
| ORL | 0.740 | 0.739 | ||
| PHI | 0.422 | 0.420 | ||
| POR | 0.495 | 0.485 | ||
| RSL | 0.409 | 0.414 | ||
| SEA | 0.713 | 0.732 | ||
| SJ | 0.476 | 0.483 | ||
| TOR | 0.784 | 0.790 | ||
| VAN | 0.509 | 0.503 |
From the table above notice that TOR (Toronto) has the most amount of salary inequality followed closely by LA, NYCFC, ORL and SEA. In terms of income equality, CLB (Columbus) is the most equal followed by DAL, MTL and DC.
Over the last few seasons here are two charts of team Gini coefficients (excluding NYCFC). The first chart is team by team Gini coefficients for Base Salary.
The second is team by team Gini coefficients for Guaranteed Compensation.
While there has been some variation in how equal (or unequal) salaries are distributed among MLS clubs, overall many teams have similar levels of Gini coefficients; most likely due to long term contracts for relatively high paid MLS players.
