The prophet Jacob said seeking for riches is OK if we first seek the Kingdom of God, and if we seek riches for the right intent—for righteous purposes.

But before ye seek for riches, seek ye for the kingdom of God. “And after ye have obtained a hope in Christ ye shall obtain riches, if ye seek them; and ye will seek them for the intent to do good—to clothe the naked, and to feed the hungry, and to liberate the captive, and administer relief to the sick and the afflicted. (Jacob 2:18-19)

First, we should seek for the Kingdom of God and do His will. Then we can seek for riches—but with the intent to do good. President Gordon B. Hinckley commented:

The Lord will love us, I think, to the degree to which we lift and bless those in distress. I believe that with all my heart, mind, and soul. The accumulation of means is not a bad endeavor when those means are used to bless the needy of the earth (Discourses of President Gordon B. Hinckley, Volume 2, Intellectual Reserve, 2005, p. 593).

It is acceptable to seek for riches if we are doing it for the right reason: to support our families, to build the kingdom of God, and to serve our fellowmen.
