The rationale for kicking out a skilled professional who's been in the country for years without problems is that the health expenses of his weight are too high. I look forwards to their expulsion of high-performance athletes lest the government have to shell out for their decades of lingering dementia care, which after all are astronomical compared to the price of a funeral for someone who weighed 130 Kg and died at 50.
