For many white Christians, giving a tenth of their income guarantees their status as good stewards. Others insist that everything belongs God and feel the need to be good stewards of all they have. You might think this would involve sacrificial giving of their finances and time, but stewardship is more commonly used by white Christians as an excuse for being cheap.
Being a good steward allows the white Christian to save money that otherwise would have been wasted on other people. It is much easier to justify purchasing the 99 cent sympathy card instead of the $3.99 card for a bereaved friend when it is seen as an opportunity to display stewardship. White Christians often feel the call of stewardship when dining out - not while selecting the restaurant, mind you, but when calculating the tip to within a penny of 15%.
Good stewardship isn't limited to the individual, but is an aspiration for all Christian organizations. White Christian churches model stewardship for the congregation by purchasing paper thin (and paper tasting) wafers for communion instead of real bread which would be very costly, possibly approaching pennies per person.
