First of all - I always find amusing how grown people cannot cope with others disagreeing with them
I receive "disagree" reactions once in a while, but that's life. Only extremely rare there is something I'd like to ask over...
Second of all - it was not the case that you stated "Joe Lewis is a billionaire" and I disagreed with that. Not nearly the case. I disagreed with what followed.
"He can spare some especially as the stadium will earn it back in a heartbeat." - you do understand some basics from economy, don't you? About business and investments?
I mean that once upon a time he made investment into Tottenham Hotspur. He is a business man and in the future he most likely wants to sell it for higher value that was purchase price. It is a project that is run by team he has picked (in this case lead by Levy).
I constantly see some BS about how "Levy pumps money out of club", how "Spurs is operated to take out cash" etc. But I never see any explanation. When I call people out that they would explain and prove how money is withdrawn then the discussion stops there.
Now I could see the silence when Lewis would inject some money into Spurs. And that MONUMENTAL uproar that would follow if he would reclaim the same sum. But I am getting getting bit off-topic with that description.
To keep it from getting extremely long, I had two issues with the statement -
1) Building new stadium and additional earning power will have to first cover servicing the debt that was taken to build the stadium. Following that it should increase our financial muscle in terms of us being able to pay good wages for good players (once we have them). If we'd follow your model, he would lend money to club and it would be paid back to owner from the stadium earnings, it would very much defeat it's initial purpose and would hamper our long-term competitiveness, not improve it.
2) It has not been an issue about lack of resources over past years - it has been shockingly poorly spent (not invested) - across past 2 seasons we have invested ~275 mil EUR to players with very poor return. We need to use current money better not to pour in new money. Otherwise he can put in a billion (which would be 25% of his estimated worth) and we still would not improve. And following 1) then we'd have to pay all the additional income from stadium to settle the money injection that we have spent on poor player recruitment. And that would be really stupid in long term sense.
