What steps to power does Boy take in this chapter?

From the text:

He had managed brilliantly on a principle so simple that it deserves to be recorded: he set up a little company of his own by borrowing $5000 for four months; as he already had $5000 it was no trouble to repay the loan. Then he borrowed $10,000 and repaid with promptitude. On this principle he quickly established an excellent reputation, always paying promptly, though never prematurely, thereby robbing his creditor of expected interest. Bank managers grew to love Boy, but he soon gave up dealing with branches, and borrowed only at Head Office. He was now a favoured cherub in the heaven of finance, and he needed a wife who could help him to graduate from a cherub to a full-fledged angel, and as soon as possible to an archangel. So Leola had lessons in tennis and bridge, learned not to call her maid “the girl” even to herself, and had no children as the time was not yet at hand. She was prettier than ever, had acquired a sufficient command of cliche to be able to talk smartly about anything Boy’s friends were likely to know, and adored Boy, while fearing him a little. He was so swift, so brilliant, so handsome! I think she was always a little puzzled to find that she was really his wife.
