Wages in aggregate eat directly into your profits, so if you're happy with lower profits and lower wages for executives, you absolutely can raise wages. If you pay 70k/year in low-margin-per-employee industries, your will inevitably operate at a loss, but this company is not low-margin.
I would also love to see this succeed, but maybe giving employees non-voting stock would better stave off the possibility of running the business into the ground.
Of course, in that idealized world, there are no "excess profits" (profits not commensurable with risk), so it should be impossible for the company to raise wages like that anyway.
So the real question is: why is this company so profitable, and can that continue indefinitely? Or does this guy just have such a high tolerance for risk that "acceptable profits" for him are unacceptable for any possible competitors?
It actually appears more likely that employers have on average already set wages slightly above the market-clearing level in order to improve productivity and maximize profits. This is the theory of "efficiency wages" [1], which tries to explain why unemployment persists when companies could cut wages and employ more people.
There is no free lunch.

The first company may do better on margins per sale, but the second will have better quality/productivity per employee.
1. If a company is paying above-market wages, then by definition there are more people who want to work there than there are available spots, so the second company will get some of the overflow.
2. The market for a particular kind of labor (e.g. phone techs) is usually much larger than whatever market for outputs these two companies are involved in (e.g., credit-card processing), so one company paying above-market wages is unlikely to change the market wage level very much.
This could definitely break down for some very specialized jobs.
The market seems to like their performance, since they are getting more business and making more profits.
If recruiting costs 10k, and training training 6 months + 20k. That's already 30k saved. Plus no opportunity cost loss because they had enough staff to do business could be easily more than the wage increase (according to the author). That's easily already over the 30k/year difference.
Assuming the company does not even grow, but just stays still... then this should be sustainable. Whilst they are growing, losing less staff than industry average will only increase their growth.
Note, that the company was slowed down because they had to hire more staff. Those slow downs would have been worse if they could not hire as quickly, or lost staff.
Is the employee retention solely because of increased wages? I'm not sure. But that alone could save the company a lot of money.
I doubt it too. But it's not completely impossible: if a doubling of your employees salary means they increase their productivity three-fold, it might even increase your total profits (of course this depends on what the surplus rate was to begin with). The point is, since profits come from the surplus rate, which depends on productivity, increased salaries can in some cases lead to higher profits.
