I don't have a problem with schools raising as much as they can. However there have to be some guidelines so everyone is playing under the same rules.
Contracts require comittments. Breaches require financial reimbursements. Poaching or tampering requires penalties or remuneration. And salaries require limits based on market pricing, so everyone has a chance to compete.
Right now it's exactly as
@30CAT describes, a free for all to the highest bidders who can simply buy a championship by outspending everyone else.
No one wants to see that.
